β¦ Synopsis
By m&k of low t&perature spec&scopy of &Ie cry& of sym-tihloiobenzene (TCB) and sym-triiromobenzene (TBB) we have detexninud that the principal Her&erg-Telkorigins in the So + Tt tksition correspond to out-of-planeviirations The &&led active modes for TCB are: 205 cm-' (e"); 144 cm-' (a;) fkom phosphores &xx; 119 Cm-' (e" or 3:). fkom absorption. For TBB the assigned modes are: 203 cm-' (e") from phosphoreskence; -.

Doppler-limited laser-induced fluorescence excitation spectra of the origin band of the x IAl-% 'Ar system of HZCS have been recorded in zero fold and in magnetic fields up to IO kG. From analyses of the zero-tield level shifts and the profdes of magnetically sensitive lines, it is deduced that the
