In each case, the lowest energy conformers were characterized and the energy barriers between them were estimated. Ionization energies and vibrational frequencies were also computed, in order to support future spectroscopic studies with ultraviolet photoelectron spectroscopy (UVPES) and matrix isolation infrared spectroscopy (Matrix Isolation FTIR).</style></abstract><notes><style face="normal" font="default" size="100%">doi: DOI: 10.1016/j.theochem.2008.10.007</style></notes></record></records></xml>
