Abstract
He I photoelectron spectra of title compounds were recorded and assigned by MNDO-PM3 calculations and comparison with spectra of related derivatives. Substituents were found to noticeably affect the electronic structure, depending on their type and position of attachment to the ring. MNDO-PM3 calculation results become unreliable in cases of thiophenes with widely different substituent types.
