Abstract
Two series of Pr and Eu dimeric single crystals with L- and DL-isoleuc ine were obtained. The effect of the ligand chirality on the structure of the dimeric units was investigated. Well-resolved absorption, exci tation and luminescence measurements on single crystals of these compo unds as well as diluted systems down to 5 K are reported and analysed. Cooperative interaction is considered and vibronic lines are assigned based on vibrational analysis. The nature of the cooperative interact ion in the praseodymium single crystals is briefly discussed.
