Photolysis of the C2H4–HONO complex in low temperature matrices: formation of 2-nitrosoethanol
摘要:
Photochemistry of C2H4 (HONO)-H-. . . complexes in argon matrices has been investigated using lambda > 340 mn radiation of a medium pressure mercury arc. IR spectra were recorded after various periods of photolysis. The photolysis reaction was found to lead to formation of 2-nitrosoethanol that was identified for the first time. Three groups of bands showing different behavior during photolysis process and after matrix annealing were assigned to three different conformers of 2-nitrosoethanol molecule. The experimental data are supported by ab initio calculations. (C) 2003 Elsevier B.V. All rights reserved.

The HONO/SO2/N2 and HONO/SO2/Ar matrixes were subjected to UV radiation (λ > 340 nm) from a medium pressure mercury lamp. The products of the photolysis were studied experimentally by means of FTIR spectroscopy and theoretically by the ab initio MP2 method. Two species are formed in nitrogenmatrixes: the hydroxysulfonyl radical HOSO2 and identified for the first time nitrososulfonic acid HO(NO)SO2
