Vacuum ultraviolet spectroscopy and photochemistry of zinc dihydride and related molecules in low-temperature matrices.
Optical absorption spectra of thin film samples, formed by the codeposition of zinc vapor with D2 and CH4, have been recorded with synchrotron radiation. With sufficiently low metal vapor flux, samples deposited at 4 K were found to consist exclusively of isolated zinc atoms for both solids. The atomic absorption bands in the quantum solids D2 and CH4 were found to exhibit large bandwidths, beh...
متن کاملUV-induced photochemistry of methyl coumalate (methyl 2-pyrone-5-carboxylate) isolated in low-temperature inert matrices
Photochemical transformations of methyl coumalate have been studied by matrix-isolation technique. Two photoreactions were induced by UV (k > 295 nm) light: isomerisation to the Dewar form and a-bond cleavage leading to the open-ring aldehyde-ketene. The first photoprocess was found to be strongly dominating. Experimental evidence of photoreversibility of both photoisomerisation processes has b...
متن کاملLow-temperature photochemistry in photosystem II from Thermosynechococcus elongatus induced by visible and near-infrared light.
The active site for water oxidation in photosystem II (PSII) consists of a Mn4Ca cluster close to a redox-active tyrosine residue (TyrZ). The enzyme cycles through five sequential oxidation states (S0 to S4) in the water oxidation process. Earlier electron paramagnetic resonance (EPR) work showed that metalloradical states, probably arising from the Mn4 cluster interacting with TyrZ., can be tr...
متن کاملInfrared-induced conformational interconversion in carboxylic acids isolated in low-temperature rare-gas matrices
An overview of our recent studies dealing with infrared-induced conformational interconversion of carboxylic acids isolated in rare-gas matrices is presented. Extensive rotational photoisomerization studies have been performed on formic acid, which is the simplest organic acid enabling this kind of processes. Formic acid has two conformers and interconversion between them can be induced by vibr...
متن کاملInfrared spectroscopic detection of the methylgermyl (H2GeCH3) radical and its perdeuterated counterpart in low temperature matrices
The Cs symmetric methylgermyl radical, H2GeCH3(X A0), and its D5-isotopomer were detected via infrared spectroscopy in electron-irradiated methane – germane matrices via the m6 mode at 839 cm 1 and the m12 absorption at 1406 cm . ExperimentswithD4-germane –D4-methanematrices also detected absorptions from theD5-methylgermyl species upon electron exposure at 624 cm 1 (m7) and 1406 cm 1 (m3) orig...
