The spectra were assigned in terms of a simple HMO scheme, in which the redn. orbital is ligand p(7), related to p(7) of biphenyl, the transition p(6) $\rightarrow$ p(7) moves to lower energy on successive redn., and bands obsd. in the near IR-visible region are due to transitions from p(7) to higher unoccupied orbitals. Detailed assignments are directly related to those of other singly and doubly reduced azabiphenyls; the bpym dianion was characterized for the 1st time. [on SciFinder(R)]
