摘要

Two conformers (cis-cis and trans-perp) of peroxynitrous acid (HOONO) were produced from in situ photolysis of an argon matrix containing nitric acid (HONO2) at 12 K by means of an ArF excimer laser. Photoconversion between various isomers of HNO3 was achieved by irradiation of the matrix with laser emission at different wavelengths; with the aid of the observed relative intensities of IR absorption lines of each species, the UV absorption spectra of cis-cis and trans-perp HOONO were determined. The maximum absorptions, about 220 and 275 nm for trans-perp and cis-cis HOONO, respectively, are consistent with results of IR absorption recorded after irradiation of the matrix with excimer lasers at 193, 220, 248 and 308 nm.
