Study of Chemiluminescent Reactions of Metal Atoms
Abstract
Laser vaporization of thin metal films has been used as the metal atom beam source for the study of chemiluminescent oxidation reactions. Techniques have been developed and demonstrated to experimentally determine the chemiluminescent reaction stoichiometry, the relative chemiluminescent cross section vs. kinetic energy, the total scattering cross section vs. kinetic energy, the total reactive cross section (under favorable conditions), the chemiluminescent spectrum and radiative lifetimes of chemiexcited species with lifetimes in the approximate range 10-100 micro sec. The versatility of the laser vaporization metal beam source has been demonstrated by obtaining the chemiluminescent spectra for the N2O oxidation of twenty different metal atoms under essentially identical experimental conditions. A definitive measurement of a long lived chemiexcited state has been made for the Pb + N2O reaction; screening tests on Sn, Mo, and Ge oxidation by N2O suggest these reactions also produce long lived excited states.
