Solvent Dependent Electronic Absorption Band Shifts of Charge-Transfer Complex Formed between Piperidine and Tetrachloro-1,4-Benzoquinone

Abstract The electronic absorption spectrum of intermoiecular charge-transfer complex formed between piperidine as electron donor and tetrachloro-l,4-benzoquinone as electron acceptor was studied in 30 different solvents. The band shifts are discussed on the basis of dielectric, refractive index and polarity functions.
