A NEW ANALYSIS SCHEME FOR COMPLEX FORCED RAYLEIGH-SCATTERING PROFILES

Abstract

A recently proposed mechanism for complex signal profiles of forced Rayleigh scattering (Park et al. J. Phys. Chem. 1991, 95, 7121) is tested with a system of globular protein-surfactant complexes. The mechanism starts with a hypothesis of double grating of pure phase complementarity which is shown to produce extreme departures, such as decay-growth-decay type, from single exponential decay. A new analysis scheme for such a complex signal type is proposed, and it has been validated here experimentally with the dynamic light scattering results in conjunction with the FRS measurements.
