Einstein A-coefficients for rotational transitions inH 2 D + andD 2 H + molecules

  • 26 Accesses

Abstract

We have calculated Einstein A-coefficients for electric dipole transitions in the ground vibrational state of the moleculesH 2 D + andD 2 H +, between the rotational levels up to 2200 and 2000 cm−1, respectively. These A-coefficients are used for computing the mean radiative life-times of the levels. These data play an important role in analysing the spectra from astronomical objects.
