The Cologne Database for Molecular Spectroscopy, CDMS

The computer-accessible Cologne Database for Molecular Spectroscopy (CDMS) contains a catalog of radio frequency and microwave to far-infrared spectra l lines of atomic and molecular species that (may) occur in the interstella r or circumstellar medium or in planetary atmospheres. The catalog is conti nuously updated and is primarily intended to supplement existing data bases such as the JPL or NIST catalogs. Presently it contains entries for 111 sp ecies. Other sections of the database include information on the programs u sed for fitting spectra and creating the catalog entries, along with detail ed information on some spectroscopy projects performed at the university of Cologne and a list of known inter- and circumstellar molecules. The databa se can be ac:ceased online fret of charge via http://www.phl.uni-koeln.de/v orhersagen/ or alternatively via the short-cut http://www.cdms.de.
