✦ Synopsis

An analysis of the high-field Zeeman effects of (O,O), 0 + 195 cm-l, O-+254 cm-l, 0 +359 cm-1 and 0 + 1139 cm-1 vibronic transitions in the lowest triplet state of hexachlorobenzene are presented. The studies refer to crystals at 4.24( in fields of ca. 80 kG. The results show that 195 cm-l is an upper state e gI mode, 254 cm-l is probably eg but perhaps a3 %. and 359 cm-l and 1199 cm-l are a vibrations. The LIO ocular symmetry is shown to be different from 3d as far as spin-orbit selection ru es 7 are concerned (as expected from the known crystal structure) but as expected no evidence of the crystal field mixing (of D9d states) appears in the non-totally symmetric vibronic bands. The distribution of electric-dipole strength over the various spin sub-states is deduced for each type of vibronic level.
