Abstract | |||||||||||||
| This paper clescribes a computer-accessible catalog of sutxnillimcter, millimeter, and microwave spectral lines in the frequency range between O alld 10,000 GHz (i.e., wavelengths longer than 30 jm). The catalog can be used as a planning guide or as an aid in the identification and analysis of observed spectral lines in the interstellar medium, the Earth’s atmosphere, and the atmos~)heres of other planets. The information listed for each spectral line includes the frequel]cy and its estimated error, the intensity, the lower state elicrgy, aud the quantum number assignment. The catalog is continuously upclated and at present has information on 331 atomic and molecular species and includes a total of 1,845,866 lines. The catalog has been constructed by using theoretical least squares fits of pub-Iished spectra] lines to accepted molecular models. The associated predictions and their estimated errors are basecl upon the resultant fitted parameters and their covariance. Future versions of this catalog will add more atoms and molecules and update the present listings as new ciata appear. The catalog is available on-iine via anonymous FTP at spec.jpl.nasa.gov anti on the worl[i wicie web at llttl)://s])ec.j])l.llasa.gc)\~. 1 | |||||||||||||
