Supplementary angle

Ie is the true scattered intensity I e is the measured scattered intensity at angle 6, and Z i8o-e is at the supplementary angle. fa and fi are the Fresnel s coefficients for the fractions of light reflected at perpendicular incidence at the glass-air and glass-liquid interfaces, respectively ta and tx are the corresponding transmission coefficients. They are defined by the following equations ...

We consider a freely-rotating chain consisting of N bonds (segments) of length a linked linearly at a supplementary angle ip. We assume that no bead-bead interaction is operating, i.e., the chain is not perturbed by volume exclusion. Until Section 4 below our considerations are limited to the case in which this assumption is obeyed. Thus, for simplicity, the term unperturbed is omitted when we refer to wormlike chains. The wormlike chain is a continuous version... 

The Kratky-Porod wormlike chain model [20,21] is widely used for describing conformational characteristics of less flexible chains. The polymer is viewed as a semi-flexible string (or worm) of overall contour length L with a continuous curvature. The chain is subdivided into N segments of length AL, which are linked at a supplementary angle r. The persistence length q (Fig. 1) is defined as...
