Abstract
\chem{M^{+}-Bz_{n}} complexes are produced in a laser vaporization/supersonic expansion source. These complexes are mass selected in a time-of-flight mass spectrometer, and their infrared spectra (700-4500 \wn) are taken using infrared laser photodissociation spectroscopy via the argon tagging method. DFT on the \chem{M^{+}-Bz_{n}} complexes is carried out to obtain the structures and vibrational frequencies. The \chem{CH} stretch and fingerprint regions of the complexes are compared to theory and the free benzene spectrum. The far infrared spectra of \chem{Al^{+}-Bz} and \chem{V^{+}-Bz} (700-1800 \wn ) are compared to the previous spectra collected using IR-MPD and significant differences in linewidth and line position are observed.
