Coupling angle

The experimental technique used to measure the third order nonlinear susceptibilities of polydiacetylenes was developed recently at our laboratory. (15) This technique utilizes the intensity-dependent dispersion relation of confined modes of PDA films and determines by measuring the change of coupling angles with... 

Table 11.3 displays a variety of geometrical descriptors for each fluid (extending results presented in Sidebar 11.3 for a monatomic ideal gas). These descriptors include the lengths of various thermodynamic vectors ( T, P, S, V ), 0Sy coupling angle (=0TP cf. Fig. 11.2), Gramian M, and minor eigenvalue e2 of the metric M. Sidebar 11.5 describes numerical evaluation of e2. 

Figure 13. (a) Wavelength vs. coupling angle for S-120 dye on a Ag substrate (b) the minimum reflectivity vs. wavelength for the same system. The measured points are shown as open circles and the solid curves calculated from bulk values of the dielectric function for S-120 dye. The measurements were made using the Kretschmann—Raether arrangement (19).
