GENERALIZED-MODEL FOR COLLISIONAL EXCHANGE OF SOLUBILIZED MOLECULES IN MICRODISPERSE SYSTEMS

The exchange of solubilized molecules in microdisperse systems is sugg ested to occur through successive one-particle hops through fluctuatio nal channels between the droplets during their collisions with tempora ry merging. The overall transition probability is calculated as a func tion of one parameter, namely, the product of the hopping frequency an d the characteristic lifetime of the connecting channels. The model ap plies to realistic sticky collisions between droplets that cover the w hole range from one extreme case of complete randomization of their co ntents (so-called fusion-fission) to the other extreme case of one-par ticle hops. Only these two extreme cases have been treated in the lite rature.
