The spectra and dynamics of coupled vibrational states in polyatomic molecules have for a
long time been a central theme of physical chemical research (1-3). Recently, a major …

The fluorescence excitation spectrum of the S 1–S 0 (1 B 2–1 A 1) transition in jet‐cooled
toluene has been measured up to 2000 cm− 1 above the origin band. Dispersed …

The application of high-resolution pump–probe rotational coherence spectroscopy (RCS)
provides precise rotational constants of large molecules and clusters for both the ground …

The vibronic spectroscopy of ortho-, meta-, and para-diethynylbenzene (o DEB, m DEB, and
p DEB) was studied by two-color resonant two photon ionization (R2PI). The symmetry …

We give a description of the phenyl-ring-localized vibrational modes of the ground states of
the para-disubstituted benzene molecules including both symmetric and asymmetric cases …

Explicit evidence for the role of methyl rotor levels in promoting energy dispersal is reported.
A set of coupled zero-order vibration/vibration-torsion (vibtor) levels in the S1 state of para …

Molecular symmetry group analysis of the low-wavenumber torsions and vibration-torsions in
the S1 state and ground state cation of p-xylene: An investigation using resonance-enhanced …

We investigate the low-energy transitions (0–570 cm− 1) of the S 1 state of para-
fluorotoluene (pFT) using a combination of resonance-enhanced multiphoton ionization and …

A study of the vibration and vibration-torsion levels of para-fluorotoluene in the 580–830
cm− 1 region is presented, where a number of features are located whose identity is …

A companion article has been published: Molecular symmetry group analysis of the low-
