In the present study Infra-red and UV spectrum of pure and iodine doped (i.e. iodine percentage i.e.0.002, 0.02 and 0.04 are added in pure polymer solution of ethyl cellulose and benzene). The pure and different iodine doped samples were designated as P0, P1, P2 and P3 respectively). In IR spectrum, intensity of bands gradually decreases as iodine concentration increases in the polymer matrix. UV spectrum of ethyl cellulose: iodine matrix shows the formation of strong CTCs, also the formation of clath rates type of compounds and the opening closing of cage formed between EC: I2 matrices is reflected. Various band formation and shifting has been explained on the basis of present theories.
Ethyl Cellulose(EC), Doping, Infra-red (IR), Ultra violet (UV), Charge transfer complex (CTC)
