Abstract
The microwave spectrum of germylacetylene has been investigated in the region 7–36 Gc/sec. The rotational constants for the isotopic species 76GeH312C≡12CH, 74GeH312C≡12CH, 73GeH312C≡12CH, 72GeH312C≡12CH, 70GeH312C≡12CH, 74GeH313C≡12CH, 74GeH312C≡13CH, 72GeH313C≡12CH, 72GeH312C≡13CH have been determined to be 3553.78, 3572.40, 3582.04, 3591.97, 3612.55, 3531.69, 3423.48, 3551.60, 3442.89 Mc/sec, respectively. From these data the structural parameters rGeC=1.896 Å and rCC=1.208 Å are determined. If rCH is assumed to be 1.056 Å, then rGeH=1.521 Å and ∠HGeH=109.9°. Measurement of the Stark effect leads to a dipole moment of 0.136 D. Analysis of the hyperfine components of 73Ge transitions leads to a nuclear quadrupole coupling constant eQq of +32.5 Mc/sec.Keywords
