Abstract
Wavelength-resolved pump-probe measurements using 11 fs duration pulses wer e performed to study the vibronic structures of HDITC, a cyanine dye, in et hylene glycol. Ten vibrational modes were observed in the forms of quantum beats. The frequencies of these ten vibrational modes ranged from 135 cm(-1 ) to 1300 cm(-1). The relative potential displacements along these ten vibr ational coordinates were estimated by comparison with theoretical calculati ons.
