Ultra-violet and visible absorption spectra were obtained for binary solutions of titanium tetrachloride with several aromatic compounds of varying electron density on the ring. These spectra show evidence for a charge-transfer process in such systems. Quantitative absorption studies were conducted on the benzene, anisole, and diphenyl ether containing systems. Attempts to describe the data with Benesi-Hildebrand type equations were successful for the two ether-containing systems by assuming 1 : 1 complexes in the diphenyl ether and both 1 : 1 and 1 : 2 complexes in the anisole system. The benzene system shows no evidence for the formation of a complex. The absorption spectrum in this system is ascribed to contact charge-transfer absorption.
