β¦ Synopsis
Ihe photoelec:ror, and vacuum-dltraviolet absorption spectra of 1,3,5trifluor~benzenc id its fully deuterated analog were measured. The two lowest ion-k&on potentials correspond to the r levels. We find twd Rydberg series converging to the First IP and one converging to the second IP. The assignments are confiird by the similarities between the vibrational fine smxtures of the ahotoelectron and the related Rydberg bands, 'These fine s:ructUres . exhibit signiIicant differences with respect to benzene,

Laser induced fluoresccncc spectra of the L3,Wrifluorobenzene radical cation have been observed in the gas phase. Vrbronic anatysis of the excitation spectra is possiile with the conclusion that a Jahn-Teller distortion is likely present.
The magnetic susceptibility anisotropy of benzene, 1,3,5trifluorobenzene and hexafluorobenzene is obtained from measurements of the Cotton--Mouton effect on the gases. Substitution of fluorine for hydrogan results in a decrease in the magnetic susceptibility anisotropy.
