What is Internal methyl group rotation in o-cresol studied by pulsed field ionization-ZEKE photoelectron spectroscopy about?

Pulsed field ionization-ZEKE photoelectron spectroscopy and (111) R2PI spectroscopy have been applied to cis-and trans-o-cresol. The internal rotational structure in S has been re-assigned for the cis-isomer, and the potential curve for the 1 internal rotation has been determined. In the PFI-ZEKE spectra recorded via different internal rotational levels in the S 1 state, well-resolved low-frequency bands have been observed. The low-frequency bands are assigned to the internal rotational motion of the methyl group in the cation. Level energies and relative transition intensities are reproduced well by a one-dimensional rotor model with a three-fold axis potential. Potential curves for the internal rotation have been determined for both cis-and trans-o-cresol cations. The barrier height for the internal rotation is different for the two isomers in the cation, while it becomes similar in S . Contributions of steric and electronic factors to the rotational barrier are discussed.
