Abstract
The vacuum-ultraviolet (VUV) region has a long-wavelength limit (~2000 Å) where air (particularly oxygen) begins to absorb radiation, but its lower limit is a bit fuzzy. Terms such as extreme ultraviolet or soft x-ray radiation are sometimes used to describe shorter-wavelength regions. We shall here employ a more pragmatic, though still cloudy limit, namely the domain of normal incidence VUV spectrometers (~500 Å) which is roughly the domain of laboratory continuum light sources (~600 Å) and of He I photoelectron spectroscopy (584 Å). Photoionization experiments in this region began In earnest about 30 years ago. These experiments progressed from measurements of absolute cross sections to photoionization mass spectrometry and photoelectron spectroscopy, and later to photoion-photoelectron coincidence and photoelectron angular distribution measurement.(1–4) They have been supplemented by fluorescence studies and even coincidence measurements involving fluorescence and ionization.5,6 Various types of partial cross sections can be extracted from these measurements. At the present time, a large body of data has accumulated, primarily on atoms and molecules which are stable, and can be readily introduced as gases into a photoionization apparatus. Investigations of the more difficult species, which are chemically reactive, unstable, explosive, or involatile, have been performed primarily in the recent decade. Some of these molecules or radicals have gained recent interest because of their occurrence in the atmosphere or interstellar media. It is the purpose of this chapter to focus on these studies.
