✦ Synopsis

The deformable-body model and a deformational self-consistent procedure are applied in the quantitative analysis of adiabatic and nonadiabatic effects in the vibration-rotational spectra of GaH X 1 S / . By making use of 18 independent unconstrained parameters 1094 vibration-rotational transitions of 69 Ga 1 H, 71 Ga 1 H, 69 Ga 2 H, and 71 Ga 2 H have been reproduced with s Å 0.000168 cm 01 , s P Å 1.087, and F Å 1.017 1 10 16 . The molecular rotational g-factor and electric dipole moment were evaluated from spectra without application of Stark and Zeeman techniques. The mass and J dependence of the electric dipole moment and the effect of a rotationally induced reversal of polarity / GaH 0 r 0 GaH / in excited rotational states are discussed.
