Abstract
The lowest excited singlet and triplet states of the oxalyl halides, (COX)2 with X = F, Cl, and Br, have been investigated at ˇ- 4 K by optical and ODMR spectroscopy. The observed excited states are assigned as the 1, 3A u (nπ*) states of the planar trans isomers. A partial reassignment of the ground state fundamentals is presented, based on the ODMR activities in the vibronically resolved emission spectra. Variations seen in the kinetic parameters and fine structure splittings of the 3A u state in the series are interpreted in terms of oxygen- and halogen-centred spin-orbit interactions.
