英文摘要: One-color (1C), two-color (2C) resonant two-photon ionization (R2PI), and mass analyzed threshold ionization (MATI) methods have been applied to study the S <- S-0 transition and threshold ionization of p-methylanisole. The excitation energy of the S <- S-0 transition is determined to be 35,401 +/- 2cm(-1) the adiabatic ionization energy of this molecule is measured to be 63,965 +/- 15 and 63,972 +/- 15 cm(-1) by the 2C-R2PI and MATI methods. Most of the observed R2PI and MATI bands result from the in-plane ring vibrations. The frequencies of vibrations 9b, I and 7a are measured to be 393, 800 and 1168cm(-1) in the S-1 state, and 412, 811 and 1220cm(-1) in the Do state, respectively. This indicates the molecular structure in the Do state is more rigid than that in the S-1 state. (c) 2006 Elsevier B.V. All rights reserved.
