Infrared Product Spectra of Arsine-Ozone Complexes, Reaction Products, and Photolysis in Solid Argon

Codeposition of AsH3 and O3 at high dilution in argon gave a large yield of AsH3-O3 complex and a small yield of reaction products identified as cis- and trans-H2AsOH.The complex photolyzed with red light, which showed that a specific interaction within the complex markedly increased the red photodissociation probability for the O3 submolecule.The red photolysis products were H3AsO, H2AsOH, and an intermediate species tentatively identified as HAsO.Further blue and near-UV irradiations destroyed HAsO and produced HOAsO2.This AsH3 and O3 study parallels earlier PH3 work and shows that AsH3, is slightly more reactive than PH3 with O3.
