KINETIC AND SPECTROSCOPIC STUDIES OF SINGLET MOLECULAR OXYGEN

Objective


Research has been carried out on the chemical and physicochemical properties of singlet molecular oxygen, in view of its potential application as an energy carrier in the gas phase, in solutions, and even in solid state.

Projects have included the following: relative quantum yields of the first excited state from the ultraviolet photolysis of ozone; transition probabilities; relaxation of states of the solid form; energy transfer of vibrationally excited molecular oxygen in rare gas matrices; lifetime measurements of the singlet states as a function of pressure; nearest neighbour orientation in oxygen cryocrystals; spectroscopic and collisional processes in the gas phase.
It is proposed, by the five laboratories which comprise
the "European Study Group for Singlet Molecular Oxygen", to measure rates of energy transfer from and to both states of singlet oxygen (a1 delta g) and (b1 epsilon +g) in the condensed and gaseous phases. Spectroscopic studies will also be carried out to measure the "dimol" transitions, collision enhanced spactra, enhancements of transition probabilities in solid matrices, and to undertake REMI studies of upper states.
