Objective
The objectives of this research are the description of numerous phenomena of acceleration of chemical reactions by adding catalysts which assist in overcoming spin-prohibition. Two main mechanisms of spin-catalysis, spin-orbit coupling induced, and paramagnetic-exchange induced spin-catalysis, are the subject of theoretical investigations by the application of first principles electronic structure calculations of spin-orbit coupling in the following reactions: oxidative addition of Ni to water; cis-trans isomerization of ethylene; d2, catalysed by molecular oxygen and by nitric oxide; state specific reactions of Fe+(6D, 4F) with O2, H2 and ethylene; oxidation of phenols to benzoquinones in the presence of O2 and metal catalysts; decarboxylation of malonic acid derivatives, catalyses by paramagnetic ions; ortho-para hydrogen conversion, catalyzed by O2; external heavy atom effects in photochemistry.
Besides these investigations, the general theory of spin-catalysis will be further considered. This includes systematisation of spin-catalysis phenomena in photo catalysis, organo-metallic photochemistry, and in biochemistry (dioxygen binding in haemoglobin and myoglobin, catalyses and peroxidases, spin changes and functioning of metallo-enzymes including cytochrome P-450). Different models of intersystem crossing mechanisms and their manifestation by magnetic field effects in spin-catalysis will be considered.
