Improved Model of the Effective Dipole Moments and Absolute Ro-Vibrational Line Strengths of the XY2 Asymmetric Top Molecules in the X 2B1 Doublet Electronic States

Abstract

A new effective dipole moment model for the (XY₂ symmetry) molecule in a doublet electronic state is derived that includes (as special cases) all currently known models of effective dipole moment for such type molecules, and allows, at the same time, to take into account an influence of spin-rotation interactions on the effective dipole moment operator which were not taken into account in the preceding studies.
