Semi-experimental equilibrium structure (reSE) of thiophene: Attempting to resolve the heavy-atom problem with 46 isotopologues.

Microwave and millimeter-wave rotational spectra of 46 thiophene isotopologues are used to determine a new semi-experimental equilibrium (reSE) structure for thiophene. The large dataset of isotopologues-roughly twice as large as any dataset used for…
