Resonance Raman spectra of the lowest excited triplet state of chlorophyll a are obtained in benzene and in methanol by pumping at 660 nm in the Q, band and pmbing at 460 nm which is close to the absorption maximum of the T, state. Tbe spectrum observed in polar methanol differs significantly from t

Pump/probe time-resolved resonance Raman experiments were carried out for free-base octaetbylporphyrin in benzene at room temperature by using two Nd: YAG lasers, and the vibrational spectra of its lowest excited singlet and triplet states were observed. The spectrum of the S, state of OEPHz pumped
In tetrahydrofuran, acetone, diethyl ether and dichloromethane, the strongest Raman line of bacteriochlorophyll a, to be ascribed to a ring-breathing mode, appeared at 1579, 1584, 1591 and 1596 cm-', respectively, in the T, state. No discrete shift of the particular Raman line, such as that used to
Raman spectra have been obtained on resonance with the 2 'A, state of room temperature cis-1,3,5-hexatriene vapor at 290.8 nm. Overtones and combination bands of totally symmetric stretching and bending modes, both alone and in combination with an interval probably assignable as the overtone of the
