MICROWAVE SPECTRA AND STRUCTURE OF METHYLGERMYL BROMIDE

Abstract

The microwave spectra of ${CH_{3}}^{70}{GeH_{2}}^{70}Br, {CH_{3}}^{70}{GeH^{81}}Br, {CH_{3}}^{72}{GeH_{2}}^{79}Br, {CH_{3}}{GeH_{2}}^{81}Br, {CH_{3}}^{74}{GeH_{2}}^{79}Br$, and ${CH_{3}}^{74}{GeH_{2}}^{81}Br$ have been recorded from 18.0 to 39.0 GHz. Only a-type transitions were observed and R-branch assignments have been made for the ground vibrational state. From a diagnostic least-squares adjustment to fit the rotational constants, the $r_{0}$ structural parameters have been obtained. These results will be compared to the corresponding quantities in some similar molecules.
