UPPER LIMITS FOR CHEMILUMINESCENCE FROM SINGLE COLLISIONS OF 03 WITH NO, CO, H2S, AND CS2,
Abstract
Double modulated, crossed molecular beam experiments were performed which permit upper limits to be set for the production of light from single, thermal energy collisions of ozone with nitric oxide, carbon monoxide, hydrogen sulphide, and carbon disulphide. Minimum detectable signals were limited by background light levels from a temperature sensitive surface reaction involving ozone. With the apparatus walls cooled by liquid nitrogen, this reaction still generated a partially single-modulated detector noise whose dc count rate was 100/sec. Beam densities were determined with an electron-ionization stagnation detector, operated at 20 cps, and photomultiplier luminous efficiency was measured by comparison with a standard lamp. (Author)
