Summary: The two-photon spectra of biphenylene (BP) and
2,3,6,7-tetra-ethyl-biphenylene (TEBP) have been measured in the region of
the lowest two electronic transitions (31-440 nm). The S0 --> S1 transition
of BP, although group-theoreticaly allowed, is only weacly observed. The
TEBP spectrum is, for both transitions, stronger than that of BP. The
experimental data are related to the pseudoparity symmetryof alternant
hydrocarbons and to the inductive perturbation of pseudoparity selection
rules. Due to the enhancement, the TEBP spectrum shows additional spectral
structures with respewct to BP, among which the weak onset of the S0 --> S1
transition around 23100 cm**-1.
