Cirloganu, O. Przhonska and other // Chemical Physics. - 2004. - P. 171-183.https://dspace.nuft.edu.ua/handle/123456789/10689The determination of the spectral position of the excited states and orientation of the transition dipole moments of polymethine molecules is experimentally measured using two methods: the steady-state fluorescence anisotropy method, and a two-color polar¬ization-resolved pump-probe method. This novel use of the pump-probe method is described in detail and a comparison to the flu¬orescence method is given. Quantum-chemical modeling on the effects of the bridge structure in the polymethine chromophore on the linear absorption spectrum is also discussed.otherorientation of transition dipole momentsanisotropyexited-state absorptionpolymethine dyeориентации дипольных моментов переходованизотропиявозбужденное состояние поглощенияполиметиновые красителиорієнтація дипольних моментів переходіванізотропіязбуджений стан поглинанняполіметинові барвникикафедра харчової хіміїArticle
