Time-resolved light scattering method

Time-resolved light scattering method, wha-ein the spinodal curve is measured based on vanishing mutual diffusivities. [Pg.10]

Polyamide (6) was irradiated with a single 20 ns flash (530 nm) in A. iV-dimethyl-ac tamide. The kinetics of the cis to trans isomerization of backbone azobenzene residues was followed by time resolved optical absorption, and the subsequent conformation change of the total polymer chain by time resolved light scattering. Before each laser e eriment, the polymer was brought to a compact conformation by eontiimous ultraviolet irradiation, and then the unfolding proce was traced by the laser flash photolysis method. [Pg.39]

Table II Space- and Time-Resolved Measurements from Inelastic Light Scattering. All methods are suitable for nonequilibrium conditions. Here, RS refers to Raman scattering, CARS to coherent anti-Stokes Raman spectroscopy, and RIKES to Raman-induced Kerr effect.

In this article we have concentrated on the uses of X-ray scattering from synchrotron radiation for the study of microtubule polymerization. Historically the main tool for monitoring microtubule assembly has been UV light scattering or turbidimetry [2], and this method is also capable of revealing the oscillations [23, 24], The method is sensitive, easy to use, and available in most laboratories. It is therefore appropriate to ask what additional information one can gain from time-resolved X-ray scattering. [Pg.27]
