A series of reactions may occur when the nitrous acid and naphthalene inside the atmospheric aqueous phases is exposed to sunlight. This article devotes to investigating from a microscopic angle the reaction mechanism and kinetics of this system using laser flash photolysis technique with an excitation wavelength of 355nm. The main research results are listed as below:(1) The OH quantum yield FOH for the photolysis of HNO2 in the aqueous phase was determined to be 0.234 and the absorption spectrum of OH radical was recorded as well.
