Abstract
Complexes of the peroxy radical and the hydroxy radical with CO2 have been investigated with FTIR spectroscopy. The peroxy radical-CO2 complex was for med on the surface of growing argon matrices by codepositing peroxy radical s and CO2. The hydroxyl radical-CO2 complex was formed on photolysis (266 n m) of the matrix isolated peroxy radical-CO complex. The bands were identif ied from concentration dependencies, H to D shifts and by photolysis experi ments. In the photolysis experiments the correlation coefficients between d ata series - decay and growth curves - and the degree of photolysis of the bands were calculated. Based on these data the bands were then assigned. Th e correlation coefficients also provided information about reactant/product relations. Ab initio calculations on the SCF level have been carried out i n order to investigate the relations between complex structure and spectral shifts. (C) 2001 Elsevier Science B.V. All rights reserved.
