Abstract

Theoretical calculation results show that electron flow occurs from xanthene to phenyl ring within the Rh101+ after its electronic transition from ground state (S0) to first excited state (S1). Time and frequency resolved transient grating (TG) spectroscopy is then conducted to seek the experimental evidence. Through Fourier analysis at different wavelengths of TG signal and their specific value spectra, vibrational enhancement corresponding to electron acceptor chromophore (phenyl ring) is observed. So the ultrafast vibrational energy redistribution process is detected experimentally and the direction of electron flow is confirmed.
