Sample test files for error checking
A collection of files useful for checking JCAMP-DX programs have been assembled from various sources. Some provide error free information, while others are more of the nature of an "assault course for JCAMP-DX". Some FAQ on scientific data formats (including JCAMP-DX) have been collated by Ilana Stern and posted at a number of sites.
There are several other data formats commonly found in scientific laboratories such as NUTS for NMR and netCDF for MS and chromatography.
A company that for many years specialised in offering not only interfaces to equipment, but converters between data formats was Galactic Industries Corporation now Thermo Fisher Scientific.
Their product, GRAMS, uses .SPC binary files and a number of sites offer spectra in this format. Thermo offer a SPC Developers Kit for programmers to create their own file converters etc. Try their searchable database of IR and Raman spectra.

JSmol - from 2013
The open source HTML5/JavaScript package of JSmol incorporating JSpecView and Jmol was first released in October 2013. JSmol is a JavaScript framework that allows web developers to create pages that utilize either Java or HTML5 (no Java), at will. This enables Jmol to display interactive 3D molecular structures on devices that do not have Java installed, or for which Java is not available (such as smart phones and some tablet computers, e.g. iPad) or has not been installed because of concerns for Java being a security threat.
Since the latest Javascript code is generated from the Java via a transpiler, the JAR files are available still and can be downloaded for off-line display and processing (JSpecView is ~1 MB and Jmol is ~11 MB).
JSmol is integrated fully with JSME as well and an example that uses all 3 involves the use of the JSmol on a webpage that calls servers in Frederick, Maryland (NIH resolver, for name-to-structure) and Lausanne, Switzerland (nmrdb, for structure-to-spectrum). By drawing a structure in JSME or by simply providing a name of a molecule and submitting the information then within about 10 seconds simulated NMR spectra (H and/or C) are displayed and this allows for changes to the structure to be made and resubmitting so that the spectra can be compared. The H or C atoms in the 2D and 3D molecular structures displayed are linked to the peaks in the spectra. Clicking on an atom or on a peak will highlight both in the displays.
More details are in Spectroscopy Europe 26(5) 15-17, 2014
JSpecView (2006) and merged with Jmol 2012
The HTML file (acetophenone.html) that calls these files gives an example of linking spectra to molecular display and loads a single Block file of spectra and includes MOL files and animation file (xyz) containing the vibration vectors. When peaks in the IR are selected in the JSpecView spectral display the appropriate FRAME in the xyz file is displayed.
For the NMR displays the peaks are linked to the atom (H or C) that are responsible for the peak seen.
For the MS display the highlighted peaks are linked to the fragment responsible
Jmol is another Open Source project originally available from Sourceforge. The JSpecView and Jmol applets were merged in early 2012 after collaboration with Prof Bob Hanson at St Olaf College. Bob has made numerous enhancements to the code and taken on the future development since my retirement.

jcamp files
The repository comes with four folders containing JCAMP-format files: infrared_spectra/, mass_spectra/, raman_spectra/, and uvvis_spectra. These were downloaded from freely-available internet databases, and can be used as example format files.
In 1988, the Department purchased a diskless Perkin Elmer 1605 FTIR. To help in the process of being able to store the IR spectra recorded, two Pascal programs were written. The first to capture the files via the serial port (RS-232) and the second to display the data.
For information on the first program, FTtoPC, and other DOS utilities to convert files obtained from various instruments to JCAMP-DX format, see our JCAMP-DX utility page.
The original display program was totally rewritten in C++ and the code licensed to MDL in 1998 for incorporation into their plugin CHIME. Our contract with MDL has now finished (November 2005) but we will endeavour to be involved with future upgrades to the CHIME plugin. The last release (2.6 SP6) was April 2004 and this is available from the MDL web site..
In March 2006 we released JSpecView as an Open Source project at Sourceforge. A report on this is published in Chemistry Central Journal 2007, 1:31 (07Dec2007). The JAVA applet and application along with source code is being developed with JAVA 1.5+.
In some of the demonstrations and examples we show the use of links between spectra and molecular graphics display such that clicking on peaks in a Mass Spectrum will highlight the relevant FRAGMENTS in the molecule, clicking on peaks in the IR spectrum will highlight the relevant BONDS or animate the vibrational mode and clicking on peaks in the NMR will highlight the appropriate protons or carbon atoms. See below for more details on how to set up these links.
Justification
With the widespread use of the WWW growing so unbelievably fast, the idea of being able to link not only molecular coordinates via MOL (PDB) format to a document, but being able to display various types of spectra seemed a wonderful opportunity to enhance the teaching of spectroscopy. To that end, problem sets can be established of known and unknown samples to view. See a makeup demo of how this might look. The possibility of sub-structure searches returning structures and spectra can now be accomplished.

A set of Python utilities for reading JCAMP-DX files.
The JCAMP_calc_xsec() function is intended to takes as input the result of the JCAMP_reader() function and to convert the x data to wavelength in microns, and the y data to cross-section in units of m^2 for gas concentration of 1ppm at standard atmospheric pressure and temperature, across a path length of 1 meter. The JCAMP_calc_xsec() function takes as input the data dictionary jcamp_dict, and manipulates that dictionary directly without having a separate return value. Changes to the dictionary may including adding the fields:
and modifying the fields:
The optional arguments wavemin, wavemax are used if the user wishes to truncate the data to only a desired spectral range. For example, setting wavemin=8.0 and wavemax=12.0 means that the returned data arrays will only contain data corresponding to those wavlengths. If the skip_nonquant optional input argument is used, then any input spectrum that does not have the complete path_length and partial_pressure fields in its dictionary will be passed without modification. (That is, no conversion to quantitative cross-section will be attempted.) If this option is set to True, then if the code finds missing data, it will attempt to generate a quantitative cross-section by guessing the missing values. Based upon NIST’s infrared database, typical values for guessing here are partial_pressure = 150.0 mmHg and path length = 0.1 m.
You can view a notebook demo in the doc folder to see how you can produce a series of plots showing spectra.

Creating links between spectra and 3D molecular graphics display
The JavaScript code can be handled as external files and by using an HTML template it is only necessary to change the name of the file containing the data. This can be easily done with a text editor without knowledge of HTML.
The method below shows what was used for the JAVA version of JSpecView
A sample set of JavaScript files are given below. The first establishes the arrays that will hold the link information and includes the setup for IR and both H and C NMR while the second contains the actual FTIR spectral information that is used to link the spectra to the molecular display animations of the vibration modes.
