Abstract

The He(I) ultraviolet photoelectron spectra of benzene-fused heterocycles containing AsC and PC double bond have been recorded, and interpret MNDO and CNDO/S quantum-chemical calculation carried out to assist interpretation of the data. The analysis of the spectra indicates that there is a strong interaction between the EC double bond and the π-system of the molecule. In contrast the conjugative effect of the phosphorous or arsenic lone pair gives rise to completely different spectra for 1,3-benzazaphospholes or -arsoles substituted in 1 or 3 positions.
