Monochromatic Flash Spectroscopy with Mercury Resonance Radiation

Abstract

WE have recently shown that a short duration flash of mercury resonance radiation (2537 Å) can be produced with an intensity great enough to investigate directly mercury photosensitized reactions by kinetic spectroscopy, when a powerful microwave pulse is used to excite a discharge in mercury vapour and nitrogen. Transient species have been detected and identified in several experimental systems, some of which are discussed here in outline. Compared with the energy produced in the continuum of a standard flash discharge1, the total energy of the monochromatic flash is small; but almost all the resonance radiation can be absorbed in the reaction system and the new method has several advantages including mono-energetic excitation and improved time resolution.
