CARS measurements were carried out on acridine to investigate the resonance behaviour of the totally symmetric vibration in the lowest excited triplet electronic state. The lineshapes of the observed vibrational mode were analysed for different pump laser wavenumbers by means of the transform theory in the Condon approximation. Under this condition the experimentally determined CARS excitation profile was compared with that calculated from the measured T n ← T 1 , absorption spectrum.
