Comments	"[Researchers] conclude that losses of translational plus rotational entropy of 40-50 e.u. are to be expected for many bimolecular reactions in solution, in view of the small dependence of these quantities on molecular size (table 1), and that this loss will be compensated to a variable extent by low-frequency motions in the product or transition state."
