Transient Raman spectra of the "twisted" Sr state of tetraphenylethylene and its "C analogue have been measured. The oletinic C,C, stretching frequency changes drastically on going from the So state to the S, state, supporting a twisted configuration of S, tetraphenylethylene. The CC stretching freq
The fluorescence emission from the S2 state of xanthione in benzene solution was time resolved using a Nd3' glass mode-locked laser driven light gate technique. Using a separate optical apparatus, in conjunction with the mode-locked laser, transient absorption spectta were recorded at times subseque
