Fast Beam Translational Spectroscopy
On this project we investigate the photodissociation spectroscopy and dynamics of neutral and anion species using a fast beam photofragment translational spectrometer coupled to a coincidence imaging detector.
Combustion intermediates, atmospherically important free radicals, semiconductor clusters, reaction intermediates.
Bond dissociation energies, enthalpies of reaction, photofragment yield spectra, vibrational frequencies, reaction mechanisms.
