Identifying complex Fermi resonances in p-difluorobenzene using zero-electron-kinetic-energy (ZEKE) spectroscopy (2018)
Journal Article
Kemp, D. J., Gardner, A. M., Tuttle, W. D., Midgley, J., Reid, K. L., & Wright, T. G. (2018). Identifying complex Fermi resonances in p-difluorobenzene using zero-electron-kinetic-energy (ZEKE) spectroscopy. Journal of Chemical Physics, 149(9), (094301). doi:10.1063/1.5045544. ISSN 0021-9606

The vibrations of the ground state cation (X ̃2B2g) of para-difluorobenzene (pDFB) have been investigated using zero-electron-kinetic-energy (ZEKE) spectroscopy. A comprehensive set of ZEKE spectra were recorded via different vibrational levels of th...

Hybridization and covalency in the Group 2 and Group 12 metal cation/rare gas complexes (2018)
Journal Article
Tuttle, W., Harris, J., Zheng, Y., Breckenridge, W., & Wright, T. (2018). Hybridization and covalency in the Group 2 and Group 12 metal cation/rare gas complexes. Journal of Physical Chemistry A, doi:10.1021/acs.jpca.8b07139. ISSN 1089-5639

We provide a consistent set of interaction energy curves for the Group 2 (IIA) and Group 12 (IIB) metal cation/rare gas complexes, M+-RG, where M+= Be+–Ra+ and Zn+–Hg+; and RG = He–Rn. We report spectroscopic constants derived from these, compare the... Read More about Hybridization and covalency in the Group 2 and Group 12 metal cation/rare gas complexes.

Effects of symmetry, methyl groups and serendipity on intramolecular vibrational energy dispersal (2018)
Journal Article
Tuttle, W. D., Gardner, A. M., Whalley, L. E., Kemp, D. J., & Wright, T. G. (2019). Effects of symmetry, methyl groups and serendipity on intramolecular vibrational energy dispersal. Physical Chemistry Chemical Physics, 21(26), 14133-14152. https://doi.org/10.1039/C8CP02757A

We consider two key parameters that have been proposed to be important for vibrational energy delocalization, closely related to intramolecular vibrational redistribution (IVR), in molecules. These parameters are the symmetry of the molecule, and the... Read More about Effects of symmetry, methyl groups and serendipity on intramolecular vibrational energy dispersal.

Consistent assignment of the vibrations of symmetric and asymmetric meta-disubstituted benzenes (2018)
Journal Article
Kemp, D. J., Tuttle, W. D., Jones, F. M., Gardner, A. M., Andrejeva, A., Wakefield, J. C., & Wright, T. G. (in press). Consistent assignment of the vibrations of symmetric and asymmetric meta-disubstituted benzenes. Journal of Molecular Spectroscopy, 346, https://doi.org/10.1016/j.jms.2018.02.002

The assignment of vibrational structure in spectra gives valuable insights into geometric and electronic structure changes upon electronic excitation or ionization; particularly when such information is available for families of molecules. We give a... Read More about Consistent assignment of the vibrations of symmetric and asymmetric meta-disubstituted benzenes.

Accurate interatomic potentials were calculated for the interaction of a singly charged carbon cation, C+, with a single rare gas atom, RG (RG = Ne–Xe). The RCCSD(T) method and basis sets of quadruple-ζ and quintuple-ζ quality were employed; each int...
