Fast Beam Translational Spectroscopy

Synopsis:

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.

Molecules studied:

Combustion intermediates, atmospherically important free radicals, semiconductor clusters, reaction intermediates.

Information obtained:

Bond dissociation energies, enthalpies of reaction, photofragment yield spectra, vibrational frequencies, reaction mechanisms.

Project members:

Paul Crider

Aaron Harrison
