The kinetics of chemical reactions in solutions can be best described by a theory established by Hendrik Kramers in the 1940s, which links Einstein's study of Brownian motion with the theory of rate Until now, it has not been possible to determine the parameters of small molecules predicted by Kramers' theory Now, Hoi sung Chung and William Eaton have monitored photons emitted by a single molecule during protein folding, and found that internal friction contributes a lot to Kramers' diffusion coefficient The "transition path time" of protein folding measured by them is the first qualitative analysis of Kramers diffusion coefficient and "free energy barrier height" in any system.
