✦ Synopsis

Weak molecular interactions such as those in pyridine-iodine, benzene-iodine and benzenechloroform systems oriented in thermotropic liquid crystals have been studied from the changes of the order parameters as a result of complex formation. The results indicate the formation of at least two types of charge transfer complexes in pyridine-iodine solutions. The pi-complexes in benzene-chloroform and benzeneiodine mixtures have also been detected. No detectable changes in the inter-proton distances in these systems were observed.
