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.
