✦ Synopsis

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 frequencies of the phenyl rings are discussed in relation to the zwitterionic nature of this S, state.
