Where can I download data chromatography, spectroscopy, collection of spectra: Data should be freely available. The data should be presented in the form of files of numerical formats (* .doc, * .txt, * .xls).
You can find electronic spectra (absorption, emission) of some organic molecules, in text format, on PhotoChemCAD. https://omlc.org/spectra/PhotochemCAD/index.html
A method is presented for extracting individual component spectra from gas chromatography/mass spectrometry (GC/MS) data files and then using these spectra to identify target compounds by matching spectra in a reference library.
