Absorption Spectra Studies.-Spectrophotometric data for chloroform solutions of these chelates paralleled closely those previously obtained'for the simple 8-yuinolinol chelates, except for mcasurable bathochromic shifts in absorption bands. Comparable shifts appear in the spectra of other 5, 7-dihalo-8-quinolinol chelates.'js7 In every instance, spectra for solutions of the 1 to 4 and the 1 to 5 compounds differed only in intensities,'increased ...
