Abstract
Rotationally resolved S1←S0 fluorescence excitation spectra of the lowest electronic transitions (origin bands) of tryptoline (TRY) and oxindole (OXI) have been recorded and analyzed. A higher vibronic band of OXI has also been observed and assigned. The derived inertial parameters from the fits provide detailed information about their conformational or tautomeric structures in both the ground and excited electronic states. These molecules exhibit significantly different transition dipole moment orientations relative to the parent reference frame of indole that signify S1 state characters having principal parentage in an 1La state for OXI and an 1Lb state for TRY.Citation
