The lowest excited triplet states of codeine and morphine and of their molecular subunits veratrole and guaiacol

, : The lowest excited triplet states of codeine and morphine and of their molecular subunits veratrole and guaiacol. Photochemistry & Photobiology 47(5): 661-668

The lowest excited triplet T1 states of the two alkaloids, morphine and codeine, have been investigated by ODMR and emission spectroscopy. The electronic character of their T1 states could be determined by comparing the T1 properties with those of the constituent parts guaiacol and veratrole. The T1 properties, e.g. phosphorescence spectra, zero-field splitting parameters and triplet sublevel selective decay rates are very similar for the constituent parts and the alkaloids. Thus, in analogy to veratrole and guaiacol, the T1 state of codeine and morphine is assigned to a .pi.pi.* state mainly localized on the benzene ring and the attached alkoxy and hydroxy groups. There is no evidence for a contribution from the other subunits, trialkylamine and unsaturated alcohol, to the T1 state of codeine and morphine.
