DEFORMATIONAL SELF-CONSISTENT APPROACH TO QUANTITATIVE-ANALYSIS OF ADIABATIC AND NONADIABATIC EFFECTS IN VIBRATION-ROTATIONAL SPECTRA OF GAH X(1)SIGMA(+)

The deformable-body model and a deformational self-consistent procedur e are applied in the quantitative analysis of adiabatic and nonadiabat ic effects in the vibration-rotational spectra of GaH X(1) Sigma(+). B y making use of 18 independent unconstrained parameters 1094 vibration -rotational transitions of (GaH)-Ga-69-H-1, (GaH)-Ga-71-H-1, (GaH)-Ga- 69-H-2, and (GaH)-Ga-71-H-2 have been reproduced with sigma = 0.000168 cm(-1), sigma = 1.087, and F = 1.017 x 10(16). The molecular rotation al g-factor and electric dipole moment were evaluated from spectra wit hout application of Stark and Zeeman techniques. The mass and J depend ence of the electric dipole moment and the effect of a rotationally in duced reversal of polarity +GaH- --> -GaH+ in excited rotational state s are discussed.
