Microwave Spectra of Thiophene, 2‐ and 3‐Monodeutero, 3,3′‐Dideutero, and Tetradeuterothiophene. Structure of the Thiophene Molecule
摘要:
2- and 3-monodeutero, 3,3′-dideutero, and tetradeuterothiophene have been prepared and their microwave spectra recorded together with the microwave spectrum of ordinary thiophene (C4H4S). Lines originating from the 4% content of C4H4S34 and the 2% content of C3C13H4S in ordinary thiophene (both the 2- and the 3-C13 species) were also identified. For all isotopic species rotational constants of high accuracy were obtained. The total material is sufficient for a complete determination of all the 8 geometrical parameters of thiophene.
