The critical behaviour of n-octyl pentaoxyethylene glycol in aqueous solutions of sodium chloride was investigated by quasi-elastic light scattering and viscosity measurements. The apparent hydrodynamic radius of the non-ionic micelles increases by addition of salt even at temperatures far from the

β¦ Synopsis
The triplet lifetimes of a series of substituted benzophenones in SDS micellar solution are controlled by the availability of hydrogen atoms from the surfactant.
A specific effect of the micellar environment is pointed out and rationalized by the introduction of a location parameter.

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
The kinetics of geminate processes of ground and excited diphenylmethyl radical pairs have been examined in micellar solution using laser photolysis techniques. The radicals do not escape from the micelles in the submicrosecond time scale in which geminate processes-which are controlled by spin evol
