Photochemistry of water-fluorine complexes in solid argon: infrared spectra of HF--HOF, HO--HF, and FO--HF complexes

Abstract

Codeposition of H 2 O and F 2 in excess argon on a cold window at 12±1 K gave new absorptions for the Lewis acid-base H 2 O--F 2 complex. Photolysis of this sample with 220-1000-nm light formed several new products. Ab initio calculations using HONDO 7.0 and the DZP basis set were performed to support the identification of new F 2 +H 2 O product complexes. HF--HOF, FH--FOH, and FH--OHF exhibited v s (HF) modes at 3877.9, 3781.3, and 3638.0 cm -1 , respectively
