✦ Synopsis

Absolute rate constant& k, of the reaction OH + HN03 were determined using a puked laser photolyskresonance ab_ sorption technique_ The measured value in cm3 mol-' s-l at 230. lolo k(l-16 Torr HN03) = 7.57 + 0.64. k(S00 Torr N2) = 7.20 f 0.66 and k(600 Torr SFe) = 8.37 f 0.45. indimtc that any pressure effect on k at 297 K is less tharr the e)cperimental uncertainty of 10%.

The magnetic field dependence of the lifetime of the benzophenone ketyl-SDS-derived radical pair in SDS micellar solution is divided into three regions. In a low magnetic field ( ~0.3 T) the lifetime increases steeply, it exhibits a square dependence on the magnetic field strength between 0.3 and 2
