Photoionization Investigation of Iodine Molecules and Clusters in a Supersonic Molecular Beam.

Abstract

A nozzle was designed and constructed which is to produce clusters of iodine molecules in the gas phase. Preliminary tests were conducted. A partial photoion yield curve for the production of iodine molecular ions was obtained for the wavelength region fo 1216-1254 A and 1299-1346 A at an optical resolution of 1.75 A. The adiabatic ionization potential of molecular iodine was determined to be 9.309 + or - 0.006 eV with a spin-orbit splitting to the next highest electronic energy state of 0.645 + or - .006 eV. Many autoionization features were observed, but because of the limited range of the wavelength study they were not assigned to Rydberg states.
