Maxwell-Helmholtz-Drude formula,

Figure 7.25. Thickness dependence of simulated ATR spectra of model organic film at galena-water interface. Simulation were performed for angle of incidence of 36°. Refractive indices for IRE, galena, and water were n-i = 2.4, 02 = 3.91, and 7)4 = 1.26, respectively, and /f4 = 0.036. Thickness of galena layer was taken as c/2 = 10 (jim. Optical constants of organic film were chosen to be close to those of lead xanthate but approximated by three-oscillator Maxwell-Helmholtz-Drude formula with fco = 2.5 yj =20 cm j = 1,2,3) vqi = 1200 cm ...
