J/A+AS/114/175      Einstein A-coefficients in CS transitions    (Chandra+ 1995)

Einstein A-coefficients for vibrational transitions in CS Chandra S., Kegel W.H., Le Roy R.J., Hertenstein T. <Astron. Astrophys. Suppl. Ser. 114, 175 (1995)> =1995A&AS..114..175C (SIMBAD/NED BibCode)
ADC_Keywords: Atomic physics Keywords: ISM: molecules - molecular data - star: abundances Description: Einstein A-coefficients for vib-rotational transitions in CS isotopomers, for vibrational quantum number v up to 20, rotational quantum number J up to 140, and {DELTA}v up to 4, are calculated. The change in J is governed by the selection rules {DELTA}J=±1. These coefficients play an important role in astronomy, as CS has been observed in a number of astronomical object. File Summary:
