Abstract

Multiple vibrational mode coupling that induces the missing mode effect and Duschinsky rotation on the potential energy surface of the S1 state in the Cy3 molecule was clarified by real-time ultrafast spectroscopy with a few-cycle laser pulse. The contributions of homogeneous and inhomogeneous dephasing to the total dephasing time were found to be 55% and 45%, respectively.
