The molecular modulation spectroscopic technique was employed to study the kinetics of NO3 radicals produced in the 253.7 nm photolysis of flowing gas mixtures of HNO3/CH4/O2 at room temperature. By computer fitting of the NO, temporal behavior, a rate coefficient of (2.3 ? 0.7) x lo-'' cm3 molecule
The luminescence quenching of Ru(bpy):' by molecular oxygen on a porous silica and controlled porous glass was studied at the 253-353 K temperature range. The reaction was observed to take place by a mixture of an Eley-Rideal (ER) and a Langmuir-Hinshelwood mechanism. The relative contribution of th
