Scattering of laser light off molecules in solution can yield previously unknown information on the kinetics of ionic chemical reactions. Yin Yeh and Norris Keeler (Lawrence Radiation Laboratory) have studied solutions of simple salts in chemical equilibrium. Ionic reactions occur spontaneously in such solutions, dissociation of molecules and association of ions causing continuous local variations from equilibrium; the relaxation time for return to equilibrium gives the rate of the ionic reaction. These reactions are too fast and involve too few molecules for standard chemical‐kinetic methods to work.
