Spectrometric Techniques, Volume II provides information pertinent to vacuum ultraviolet techniques to complete the demonstration of the diversity of methods available to the spectroscopist interested in the ultraviolet visible and infrared spectral regions. This book discusses the specific aspects of the technique of Fourier transform spectroscopy. Organized into five chapters, this volume begins with an overview of the large number of systematic effects in the recording of an interferogram. This text then examines the design approach for a Fourier transform spectrometer with focus on optics. Other chapters provide a brief background to outline the scientific usefulness of Fourier spectrometers and present a calculation giving the optical path difference required to solve a Doppler-broadened spectral feature. This book discusses as well the importance of good mechanical design to minimize sampling error contributions by mechanical mechanisms and resonances. The final chapter deals with photon counting techniques to measure dispersed radiation. This book is a valuable resource for spectroscopists.
Photoelectron emission from solid tungsten, nickel, and semitransparent aluminum cathodes exposed to ultraviolet radiation between 256 A and 1216 A has been studied with planar retarding-potential analyzers. The resulting current-voltage diagrams (CVDs) for these three metal cathodes are essentially identical. The CVDs comparing photoelectron emission from the front and rear surfaces of the semitransparent aluminum cathode are also identical. A retarding-potential analyzer having near-spherical geometry was also used to obtain CVDs for the photoelectrons emitted from the rear surface of a thin-aluminum cathode. The value of retarding potential detectors for limited spectral resolution in the...
