Abstract
Abstract The microwave spectroscopic and theoretical investigation of the 2-ethynylthiophene was carried out. Rotational spectra of eight isotopologues in their natural abundance were measured and assigned, which allowed a precisely structural determination. The substituent effect on the π-electron distribution was revealed by comparing the molecular electrostatic surface potentials of thiophene, 2-chlorothiophene and 2-ethynylthiophene.
