High Resolution Multiphoton Ionization Photoelectron Spectra of OCS
Abstract:
Using a Nd:YAG pumped pulsed dye laser-wavelength extender as UV light source, the multiphoton ionization of o CS was studied in a supersonic molecular beam with a Time of Flight mass spectrometer and a Magnetic Bottle Time of Flight photoelectron spectrometer. The intermediate resonant states of OCS were obtained from the mass selected MPI spectra by scanning the laser wavelength. From 2+1 MPI photoelectron spectra at different resonant wavelength the vibrational levels of OCS+ ion in electronic ground state X2 H3/2,1/2 were assigned and their X2II spin-orbital splitting was determined to be 0.046eV. The non Franck-Condon behavior between the Rydberg intermediate state and the ionic state has been discussed.
