Summary:Abstract Polarized absorption spectra of [Cr(C6H6)2]I in the visible and the ultraviolet region were quantitatively determined by Tsuchida-Kobayashi’s microscopic method using a single crystal. Visible and ultraviolet absorption spectra in solution and an infra-red spectrum in potassium bromide disks were also determined. From the results of the measurements, it was concluded that the electronic state of the benzene rings in [Cr(C6H6)2]I deviates greatly from the state of free benzene and that the π-electrons of the benzene rings are attracted remarkably toward the chromium ion to form firm linkages.
