Abstract

and molar volume were measured. FTIR and UV spectra were recorded at 400–4000 cm1 and 200–850 nm, respectively. Optical energy gap (Eopt.), Urbach’s energy (Eu), and refractive index (n) were calculated using absorption spectrum fitting (ASF) and derivation of absorption spectrum fitting (DASF) methods. Molar refraction (Rm) and molecular polarizability (am) have been calculated according to (ASF) method.
