英文摘要: The band origin of the S-1 <- S-0 transition of p-methylstyrene is determined to be 34,276 cm(-1) by one color resonant two photon ionization (1C-R2PI) method, which is red shifted by 3811 cm(-1) with respect to that of benzene. This indicates that the interaction of the methyl and vinyl groups with the ring in the S-1 state is greater than that in the So state. The active vibrations assigned from the R2PI spectrum are found to be the in-plane ring modes. The bands at 399, 613, 724, and 786 cm(-1) are assigned to the vibrations 9b, 6b, 12, and 1, respectively, and discussed in detail. The experimental results are well supported by ab initio and density functional theory (DFT) calculations. (c) 2006 Published by Elsevier B.V.
