Abstract
Rotational spectra of trifluoro‐iodo silane observed with a video microwave spectrometer were fitted to the following molecular constants: B=1118.84 Mc/sec, eqQ estimated to be −1450 Mc/sec. Since dSiF and φFSiF have been found in other molecules to be 1.560±0.005 Å and 108°30′±1° these parameters were assumed, and dSiI was found to be 2.387±0.02 Å. This observed Si–I bond shortening has been found in other molecules and is attributed to ionic and double‐bond character.Keywords
