✦ Synopsis

Parker's (+, -) pseudo-parity labels for the clcctronic sla~cs of ~ltcrnnnt hydrocarbons provide explicit selection rules governing perturbations of multiphoton forbidden optical transitions. One principal Tiding is that inductive substilucnl cffccts in bcnzcnc dcrivalivcs should significantly cnhancc the two-photon 'La transition, but ought to h;lvc little inlluencc on the two-photon 'Lb lrensition. The two-photon fluorcsccncc excitation spcclrn of bcnzcnc and monofluorobcnzcnc arc seen to confum thcsc prcdiclions

Rotational perturbations are identified in Doppler-free two-photon spectra of the 14' 9 and 14r 0 1' 9 vibronic bands in ChH6. Evidence is found that Coriolis coupling between some of the rotational levels of two distinct vibrational states within St is the mechanism responsible. Thin coupling mecha

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 (310-440 nm). The S, -+ S, transition of BP, although group-theoretically allowed, is only weakly observed. The TEBP spectrum is, for both t
