✦ Synopsis

spectra

The resonance Raman excitation profiles of the 1 : 1 electron donor-acceptor complex between hexamethylbenzene and tetracyanoethylene (TCNE) have been gathered and analyzed using transform theory. Scaling factors and non-Condon factors have been obtained for the excitation profiles of the donor-acceptor stretch at 168 cm-t, the C=C stretch at 1550 cm-~, and the CN stretch at 2223 cm-5, and used to estimate the change in donor-acceptor distance and in TCNE bond lengths in the charge transfer excited state.

Raman spectrum of the tetracyanoethylene-hexamethylbenzene EDA complex was recorded using seven lines of an Ar laser and one from a Kr laser. By comparison with spectra recorded of the donor and acceptor moIecuks separately, it was found that some of the lines of the complex were up to 393 times str
