It is a familiar problem in high resolution spectroscopy: You would like to spectroscopically analyze a certain molecule, but you do not know the exact position. You should be able to find it, for example, in the HITRAN database with the help of the MOLSPEC software. However, the number of molecules is limited here. In addition, generated spectral data may not be free of errors. A spectrum that is ascertained with experiments is more revealing, but more difficult to obtain.
LASER COMPONENTS created a literary compilation as an aid; this compilation can be downloaded for free. The Spectra catalog contains spectra from 37 molecules or molecule radicals, which are measured using TDLAS (tunable diode laser absorption spectroscopy) and often have more than one spectral position per species. The measured spectrum of each spectral position is depicted on one page together with the citation. May the "Catalog of Spectral Positions" find as many users as possible!
Remarks:
- This catalog currently only exists in PDF format (approx. 4 MB) and can be downloaded for free.
- The spectroscopic community is called upon to actively partake in the updating of this database. Scientists are asked to provide us with their current publications and measurement data at any time and we will continue to integrate this information into the catalog.
- The basic principles of TDLAS are explained in the application report that goes by the same name. This report is also available for download.
