The electronic structure and substituent effects (SEs) in 2-bromo-5-chlorothiophene, 2-bromo-5-methylthiophene, and 2-bromo-5-nitrothiophene have been investigated by HeI photoelectron spectroscopy (PES). The observed PES bands were analyzed by combining empirical arguments and theoretical methods.
