Abstract

The semiempirical SCF-LCI method in the Jt approximation (Pariser-Parr-Pople method) is outlined (appendix) and applied to the calculation of furfural ( 1) and the carbocyclic aldehydes (2) -(7). The spectral features of (1) -(7) in the UV-Vis, region are discussed in comparison with those of the parent compounds and are found to be well reproduced by the cakulations. The absorption and emission properties of furfural are described theoretically; charac­teristic differences in relation to those ar iso-1r-electronic compounds were found. The 10nization potentials and electron affinities are derived according to Koop­man's theorem. The electron affinity (0.4ev) derived from the polarographic half­ wave potential is in good agreement with the theoretical result (0.38 ev.).
