The electronic absorption spectra of cinnamaldehyde, o-, m-, p-hydroxycinnamaldehyde and 3-methoxy-4-hydroxy cinnamaldehyde were theoretically and experimentally studied, by means of the semiempirical CNDO/CI method. The calculated and observed transition energies were in good agreement.

A series of LCAO-MO-SCF calculations, using various basis sets of Gaussian-type functions, has been made in order to study the effects of p, d, and f polarization functions on calculated one-electron properties for a 10-electron isoelectronic series of oxygen hydrides and for an 18-electron series of sulfur hydrides. Conclusions from these results suggest that several one-electron properties have a predictable, although not monotonic convergence pattern. Except for calculated field gradients, f GPF's have only a small effect on the calculated values.
