発明の名称 (英語) METHOD FOR ESTIMATING CONCENTRATION OF GENERATING HOTOCHEMICAL OZONE BY THE USE OF PUMP-PROBE METHOD, AND APPARATUS FOR ESTIMATING CONCENTRATION OF GENERATING PHOTOCHEMICAL OZONE UTILIZING THE METHOD
発明の概要(英語) A method for estimating the concentration of a generating photochemical ozone by the use of the pump-probe method which comprises irradiating the atmosphere (11) with a pump laser light (2C) to decompose ozone contained therein and form an excited oxygen atom O (1D) and react the excited oxygen atom O (1D) with steam, thereby forming an OH radical, irradiating the OH radical with a probe laser light (3e) to exite an electron of the radical, and measuring the fluorescence (12) emitted in the relaxation and transition of the exited electron with the elapse of time. The strength of the fluorescence is proportional to the concentration of the OH radical, and thus the concentration of the generating photochemical oxidant is estimated from the change with time of the concentration of the OH radical. The above method allows the estimation of the concentration of a generating photochemical ozone, without the use of a method comprising measuring the respective concentrations of a great number of types of reactive hydrocarbons and estimating the concentration of a generating photochemical ozone based on the respective reaction rates with a OH radical.
