✦ Synopsis

A large number of works have been done on double molecules. For 2,2'-Biquinoline (2,2'-BQ) (Fig-l), the studies were investigated essentially for the triplet state by various techniques; steady state ESR[1], raman and ODMR techniques [2]. Some works on the 2,2'-BQ complexes have stressed the close connection between the metal complex formation and the conformation change of the ligand molecule [1,3,4].Our interest in this molecule arises from our earlier observations on other double molecules such as 1,1'-binaphthyl and 2,2'binaphthyl [5,6] and 9,9'-bianthryl [7,8]. In the present work, the investigation was carried out experimentally on 2,2'-BQ for which original results are given.
