Abstract
Abstract The dielectric constant of the phenothiazine-iodine system in benzene has been determined at 30°C and 40°C on a dipolemeter operating at a radiofrequency of 1MHz. Simultaneous determination of density had been made on a calibrated pyknometer. The dipole moment of the donor, μD (calc.), has been compared with the dipole moment μN of 1:1 molecular complex formed between donor-acceptor at two temperatures. The μN values at 30°C & 40°C are for chloropromazine-I2 13.4 D & 12.6 D; prochloroperazine -I2, 13.5 D & 11.6 D; promazine-I2, 21.2 D & 17.3 D; pericyazine -I2, 12.9 D & 10.5 D and thioproperazine -I2, 19.6 D & 12.0 D;. High values of E HOMO for the donor molecule suggest that the phenothiazines are good donors and the possibility of molecular association with σ-acceptor iodine is from the active site at S atom in each donor. The extent of molecular association decreases with the increase in temperature.
