WebMar 21, 2024 · Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random … WebThe degree of orientation is dependent on the rotatory diffusion coefficients of the molecules. If the rotatory diffusion is slow, the flow is effective in orienting the molecules. If the rotatory diffusion is rapid, then the Brownian motion dominates the orienting tendency of the flow and the flow is ineffective.
