Studies of Diffusion-Influenced Fluorescence Quenching
The study of diffusion limited reactions has occupied a central place in chemistry for many years. When the intrinsic reaction is sufficiently rapid the rate of mass transport becomes the rate limiting step and the reaction is considered to be diffusion controlled or diffusion influenced. Previous studies of diffusion controlled reactions [1,2] have found excellent agreement between experimental results and the classic descriptions by Smoluchowski  and Collins and Kimball . We present data here that demonstrates a direct observation of non-Smoluchowski behavior of a diffusion influenced bimolecular fluorescence quenching reaction.
