Transition state theory is central to our understanding of chemical reaction dynamics. We
demonstrate a method for extracting transition state energies and properties from a …

The 193-nm photolysis of CH2CHCN illustrates the capability of chirped-pulse Fourier
transform millimeter-wave spectroscopy to characterize transition states. We investigate the …

A systematic analysis of the S 1-trans (⁠| ${\rm\tilde A} $| A ̃ 1 A u) state of acetylene, using
IR-UV double resonance along with one-photon fluorescence excitation spectra, has …

Isomerization between the cis and trans conformers of the S 1 state of acetylene is studied
using a reduced dimension discrete variable representation (DVR) calculation. Existing DVR …

Rotational analyses have been carried out for the overtones of the ν 4 (torsion) and ν 6 (in-
plane cis-bend) vibrations of the A ̃ A u 1 state of C 2 H 2⁠. The v 4+ v 6= 2 vibrational …

Rotational analyses are reported for a number of newly-discovered vibrational levels of the
S1-trans (Ã1Au) state of C2H2. These levels are combinations where the Franck–Condon …

We report novel experimental strategies that should prove instrumental in extending the
vibrational and rotational assignments of the S 1 state of acetylene, C 2 H 2, in the region of …

Franck-Condon vibrational overlap integrals for the $\tilde {A} $1$ A $ u-$\tilde {X} $1$ Σ
$$^{+} _ {g} $ transition in acetylene have been calculated in full dimension in the harmonic …

We calculate second-order vibrational perturbation theory (VPT2) anharmonic force fields for
the cis and trans conformers of S1 C2H2, and compare the results to experiment. The …

Reduced dimension variational calculations have been performed for the rovibrational level
structure of the S 1 state of acetylene. The state exhibits an unusually complicated level …
