## Abstract The semiempirical PPPβSCFβSCI method has been adapted to evenβelectron, openβshell Οβsystems by performing the SCF calculation on the lowest triplet configuration and choosing a limited set of single electronic excitations from the latter for configuration interaction. The basic approxi

Far-infrared spectra of matrix isolated HNCO, HNCS, DNCO and DNCS in argon, have been examined in the lo-50 cm-' region ot a temperature of 13Β°K. The intense bands observed are b&t explzked by rotation of the molecule. The moleculesCO~, OCS, Hz0 and DzO have also been examined and discussed briefly.
