Scattering applications

When reflection geometries are set up in modern scattering applications to study the structure of thin layers, the simplifying assumption of infinite sample thickness is not allowed, and the absorption correction becomes more difficult. Moreover, symmetrical-reflection geometry is utilized less frequently than asymmetrical-reflection geometry with fixed incident angle. Thus both cases are of practical interest.

Proteins that are near their supersaturation points in concentrated salt solutions can frequently be induced to crystallize by changing the temperature. This phenomenon, which has been used for the fractional purification of proteins (Jacoby, 1968), has found only scattered application in protein crystallization. Nevertheless, given the relative ease of precise temperature regulation, methods based on temperature alteration de-...

Operationally, the optical components used in turbidimeters and nephelometers are similar to those used in fluorometers or photometers. For example, the light sources commonly used are quartz halogen lamps, xenon lamps, and lasers. He-Ne lasers, which operate at 633 nm, have typically been used for light-scattering applications, such as nephelometric immunoassays and particle size and shape determinations. The laser beam is used specifically in some nephelometers because of its high intensity in addition, the coherent nature of laser light makes it ideally suited for nephelometric applications.

In this chapter we will describe the theory and experimental techniques of Brillouin scattering. Applications will be made to several polymeric systems and the type of information that can be obtained will be discussed. 

By a slight modification of the treatment given in Schuster and Nicholson (1928) one can obtain the following expression for the intensity of forward scattering applicable at zero concentration to particles of arbitrary size and refractive index whenever HOi /VOrV— 0... 

In this case, we will be speaking of SLS since time is not involved any more. Equation 18.6 actually represents the point of departure of the classical light scattering applications the determination of molecular weights and radius of gyration of polymer molecules. Since...
