Torsions, low-frequency vibrations, and vibration–torsion (“vibtor”) levels in the m-chlorotoluene cation [PDF]
The Journal of Chemical Physics, 2020 Zero-electron-kinetic-energy (ZEKE) spectra are presented for m-chlorotoluene (mClT), employing different low-lying torsional and vibration–torsional (“vibtor”) levels of the S1 state as intermediates. The adiabatic ionization energy is determined to be 71 319 cm−1 ± 5 cm−1 (8.8424 ± 0.0006 eV).
