✦ Synopsis

Diiiusion of I'eCl,-41i20 in ;I>-cerol (0.4 Bl) is mcnsurcd from 20 IO 60°C rhrough light scatterin_= rsperimenrs. In this tempcrnture rsnpc the solvent viscosity varies by a factor of 20. The scattering angle is varied from 30 to 1150~ to show the hvdrodvnarnic y-' behavior in the scattering wzwxcctor q_ Assuming a Stokes-Einstein relstionship D = X-B T/6-R, the _ -radiu\ R = 2.05 2 0.09 X is obraincd for ferrous chloride.
