Abstract

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 X¹ Σ⁺. By making use of 18 independent unconstrained parameters 1094 vibration-rotational transitions of ⁶⁹Ga¹H, ⁷¹Ga¹H, ⁶⁹Ga²H, and ⁷¹Ga²H have been reproduced with σ = 0.000168 cm^-1, σ̂ = 1.087, and F = 1.017 ̃ 10¹⁶. 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^- → ^-GaH⁺ in excited rotational states are discussed. © 1997 Academic Press.
