Abstract

Pulsed field ionization zero kinetic energy (PFI-ZEKE) photoelectron spectra were measured for jet-cooled o-, m-, and p-methylanisoles for the first time. The low-frequency bands observed at around the origin band in the spectra were assigned to the methyl internal rotational bands of the cations. The potential curves and the Franck-Condon factors for the methyl internal rotational motion were calculated by the one-dimensional free-rotor approximation. The potential barrier height was found to change drastically on ionization, suggesting that the electronic structure should mainly affect the potential barrier of the methyl internal rotation.
