Microwave Absorption Spectra of A1F, GaF, InF, and TIF

Abstract

Observation of various rotational transitions of four Group IIIa monofluoride allowed the Dunham coefficients Y01, Y11, Y21 and Y12 to be determined. From the hyperfine structure of the A1F, GaF and InF spectra, tbe nuclear electric quadrupole coupling constants, e qv Q, and spin-rotation coupling constant, cr, were obtained for several vibrational states, v: [FORMULA OMITTED] Stark effect measurements on GaF and InF in the ground vibrational state resulted in the following electric dipole moments: [FORMULA OMITTED]. © 1970, Walter de Gruyter.
