Molecular multiphoton ionization spectroscopy
Abstract
Multiphoton ionization spectroscopy (MPIS) is described, and several examples of its application are given. Studies of 3pz Rydberg states of the methylbenzenes and of the 1B2u state of benzene show that state assignments can be made and new multiphoton structure can be seen that is not available in one-photon spectra. MPIS of benzene in a supersonic jet demonstrates dramatic resolution improvement and indicates that natural linewidth formation can be obtained for large molecules. Attention is given to collisional effects in MPI spectra with reference to Xe and to laser enhanced collisional broadening of NO in the supersonic beam.
