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. Keywords: asymmetric top molecules in non-singlet electronic states, spin-rotation interactions, absolute line strengths, effective dipole moment operator.
