Participation of singlet oxygen in photodestruction of air-saturated solutions of coumarin dyes
Abstract
The possibility of employing ground-based Raman-scattering lidars to investigate the molecular gas concentration profile of the atmosphere is studied. The random error of the method is analyzed; the efficiency of existing Raman scattering lidars is investigated, and the gas-analytic capabilities of lidars employing excimer lasers are studied using hypothetical systems with optimum sounding wavelengths as an example. It is found that UV band excimer lasers expand the capabilities of Raman scattering lidars significantly, and make them highly promising for numerous remote (up to 1 to 2 km altitude) atmospheric gas analysis tasks.
