The solv3rochromlccqu311ons dcscnbmg rbe cifects of solvent polar~ty/polwizab~hty (IT*), solvenr hydrogen band donor acIdtry (a). and solbent hydrozcn bond xccptor bJsiaty (I?) have been determmed for scvcd Iluabundazole homologurs The s rosificlcnt ws iound to bc hnearly rclstcd to rhe Hammett o* values, and can be used 3s 3 measure of substlluent ef-ic~ts on the lumlphor. I introduction ,Uthough n 1s well known that phorophyslcal propertles ofaromatlc molecules,such as fluorescence energy and lifetimes, are very sensltlve to the type of solvent used to dissolve rhe species, rhe ekxt nature of these solvent effects has been dGxdt to detail. hlany scales for solvent polarily have besn praposcd, and the most useful app2ars to be the lmear solvat~on energy relationship dekqscd by Kamk, Abboud and
