ABSTRACT:
A method for determining the spatial and phase distribution of a liquid-vapor multiphase fluid. The method comprises adding a fluorescent monomer and a quencher to the fluid to be studied. The fluid is then dispersed and the monomer excited. The excited monomer combines with the quencher to form a fluorescent exciplex. The monomer fluorescence is predominantly in the vapor phase and the exciplex fluorescence is predominantly in the liquid phase.
