AbstractWe have performed ab initio molecular orbital calculations to find the optimized geometries and predicted vibrational spectra for the S0 and T1 states of 4-chlorobiphenyl, 3-chlorobiphenyl, and 2-chlorobiphenyl. We have obtained Raman spectra of the S0 and T1 states of 4-chlorobiphenyl, 3-chlorobiphenyl, and 2-chlorobiphenyl. We find that 2-chlorobiphenyl has a nonplanar structure in its T1 state while the T1 states of 4-chlorobiphenyl and 3-chlorobiphenyl have a nearly planar quinoidal structure. Comparison to previous EPR results for methylbiphenyls suggests that the twisting of T1 2-chlorobiphenyl is likely due to an electron withdrawing effect of the ortho substituted halogen atom.
