Matrix-isolation infrared spectroscopic and density functional theory studies on reactions of laser-ablated lead and tin atoms with water molecules

Reactions of laser-ablated lead and tin atoms with water molecules in excess argon were studied by infrared spectroscopy. Insertion products HMOH and HMO (M = Pb and Sn) formed in the present experiments and characterized using infrared spectroscopy on the basis of the results of isotopic shifts, mixed isotopic splitting patterns, stepwise annealing, changes in reagent concentration and laser energy, and a comparison with theoretical predictions. Density functional theory calculations were performed on these molecules and the corresponding transition states. Agreement between the experimental and calculated vibrational frequencies, relative absorption intensities, and isotopic shifts supports the identification of these molecules from the matrix infrared spectra. Plausible reaction mechanisms have been proposed to account for the formation of these molecules.

GENERATION, LOW-TEMPERATURE STABILIZATION, STRUCTURE, AND REACTIVITY OF INTERMEDIATES WITH LOW-COORDINATED CARBON, SILICON, AND GERMANIUM ATOMS

The mechanisms of thermal and photochemical transformations of organic and organometallic compounds which pass through formation of different reactive intermediates were investigated by low-temperature matrix IR spectroscopy.Low-temperature matrix stabilizaton of the intermediates, the primary products of these reactions, was conducted at 10-15 K.The spectral and structural parameters of the free radicals (CCl3, CCl2Br, CClBr2, CH2CH=CH2, CF2CF=CF2, CH2-CCH, CH2CN, CH2Ph, CF2C6F5), halocarbenes and their silicon and germanium analogs, and unstable molecules with double-bond silicon and germanium atoms were obtained as a result.

Matrix Reactions of Germane and Oxygen Atoms. Infrared Spectroscopic Evidence for Germylene-Water Complex, Germanone, Germanol, Hydroxygermylene, and Germanic Acid

An extensive infrared study of the photochemical reaction of germane and ozone has been performed in solid argon.Isotopic substitution at all positions and filtered photolysis provide a basis for identification of seven new molecular product species.Germanone (H2GeO), the germylene-water complex (H2O-GeH2), and hydroxygermylene (HGeOH) appeared on red photolysis and gave way to germanic acid ((HO)2GeO), its peroxo isomer (H(O2)GeOH), germanium oxide (GeO), and germanol (H3GeOH) with ultraviolet photolysis.
