Research Abstract

Photodissociation of water ice at low temperature is relevant to the interstellar surface chemistry. Production and surface reaction dynamics of H atom, O atom and OH radical are experimentally investigated in collaboration with theoretical studies of molecular dynamics and quantum chemical calculations. An original idea on the surface photochemistry at low-temperature has been proposed. In addition, interfacial reaction chemistry between solution and air has been investigated to propose new interpretations in atmospheric environmental chemistry.
