Abstract:
The emission spectrum of the specific isotopomer (70)GeS was excited in a microwave (2450-MHz) discharge and the A(1)Pi-X(1)Sigma(+) transition (270-430 nm) was photographed under high resolution on a 10.6-m Ebert grating spectrograph. The rotational analysis of 43 bands led to the determination of accurate vibrational and rotational constants. Making use of these constants, the potential energy curves for the A(1)Pi and X(1)Sigma(+) states were generated by the RKR method and Franck-Condon factors and r-centroids were computed for the bands analyzed. The present extensive high-resolution study has revealed only a few localized perturbations in the A(1)Pi (v'=4, 5, 9) vibronic states, which contrasts with the situation in the isovalent molecules such as GeO, SiS, and SiSe.
