## Abstract Aqueous environments in living cells are crowded, with up to >50 wt% small and macromolecule‐size solutes. We investigated quantitatively one important consequence of molecular crowding—reduced diffusion of biologically important solutes. Fluorescence correlation spectroscopy (FCS) was
A fluorescence correlation experiment for measurement of rotational diffusion in the nanosecond time scale is described. Using this method, the rotational diffusion coefficient of bovine carbonic anhydrase B labelled with tetramethylrhodamine isothiocyanate was estimated to be Dr = (1.14 +/- 0.15) X
