Tools

The web provides a number of free databases and search engines for spectroscopy. They assist you in finding out the absorption features of various trace gases.

We compiled a selection of tools below, which we consider very useful. Which programmes are you using? We will be glad to extend our list and share it with your peers.

Free databases and search engines for spectroscopy:

Hitran Database - High-Resolution Transmission Molecular Absorption Database

Geisa Spectroscopic Database - Gestion et Etude des Informations Spectroscopiques Atmosphériques / Management and Study of Spectroscopic Information

Mol ExplorerTM - simulation of IR molecular absorption spetra for all commonly known gases without being a specialist of HITRAN or GEISA data bases

Spectra Plot - wavelength search engine

Spectral Calculator - high resolution spectral modeling
