摘要: Sensitized fluorescence has been under continuous study ever since its discovery by Wood and Cario. Accordingly, a considerable number of review articles have appeared at regular intervals. We quote the books Mitchell Zemanski, (1) Pringsheim, (2) Massey Burhop(3) Krause, (4.5) Sciwert, (6) Kraulinya KruglevskijJ,(7) Lijnse, (8) Nikitin.(34) However, in all these reviews main attention directed toward energy transfer. Since mid-1960s an increasing interest arisen transfer quantities other than energy. These are population structures described density matrices tensors. The growing importance aspects made us attempt to give first survey activities this field. will not omit traditional altogether, but restrict ourselves most recent developments. In respect we emphasize where stand rather completeness reported work that last 60 years.
