Abstract
- Fourier-transform photon echo spectroscopy has been applied to the vibronic absorption band in dye molecule. The quantum beat between the vibronic lines has been observed in cresyl-violet and tetraphenyl-porphine doped in polymer films. The vibronic lines associated with the quantum beat have been identified with comparing the Fourier-transformed spectrum of the echo signal and the persistent hole-burning spectrum. The observed steep temperature dependence of the vibronic coherence has been discussed in comparison with the mild temperature dependence of vibrational coherence (sublevel coherence between vibronic states).
