摘要
The Raman intensities of trans-stilbene (tSB) in the lowest singlet excited (S-1) state is derived from quantum chemical calculations by the CIS method and compared with the transient Raman spectra observed under resonant and off-resonant conditions. The calculated Raman intensities of tSB in the S-1 state are useful to some extent for assigning the observed Raman bands. However, some discrepancies are found between the calculated and observed Raman intensities. The reason for such discrepancies is discussed. (C) 2006 Elsevier B.V. All rights reserved..
