✦ Synopsis

Laser fluorescence excitation spectra and dispersed fluorescence spectra of jet-cooled 3-bromotropolone and its OD derivative have been measured in the &-So region to investigate the intramolecular hydrogen bond. Only one electronic origin band has been detected, although two tautomeric forms are possible for 3.bromotropolone. This suggests that one tautomeric form is energetically much more stable than the other form.

Both fluorescence excitation and dispersed fluorescence spectra of 2-aminobenzotrifluoride in a supersonic jet show quite extensive vibrational structure due to the CF,-torsional motion in the S, and So electronic states, respectively. This structure has been assigned and results in CF,-torsional po

Raman and infrared spectra of 2-aminobenzotrifluoride, in the liquid phase, and single vibronic level fluorescence (SVLF) spectra, in a supersonic jet, have been recorded and assigned to give an almost complete set of fundamental vibration wavenumbers in \(S_{0}\). In the SVLF spectrum, the assignme
