Both fluorescence excitation and dispersed fluorescence spectra of 2-aminobenzotrifluoride in a supersonic jet show quite extensive vibrational structure due to the CF3-torsional motion in the S1 and S0 electronic states, respectively. This structure has been assigned and results in CF3-torsional potentials with parameters V3=450 cm¯¹, V6=83 cm¯¹ in S0 and V3=240 cm¯¹, V6=−67 cm¯¹ in S1. There is some evidence which points to interaction between an amino-hydrogen atom and the fluorine atoms: this may be due to hydrogen bonding or steric effects, or both.
