Effect of doping with N, Br, and F atoms on electrodynamic characteristics and physical properties of isatin-$\beta$-anil

Interaction of electromagnetic radiation (250–850 nm, 2.5–15.3 $\mu$m, and 11.5–17.1 mm) with the isatin-$\beta$-anil (C$_{14}$H$_{10}$N$_2$O) films deposited with the aid of flow coating is considered. It is shown that the modification of original structure using N, Br, and F atoms leads to frequency deviations and variations in the amplitude of luminescence and changes of the frequency dependences of the absorption coefficients relative to those of the original isatin-$\beta$-anil.
