摘要: 
A novel scale of steric substituent constant E-s(D) is defined from the correlation of the logarithms of the internal rotation rate (k(r)) at 393 K with Hancock (E-s(c)) steric constant by means of dynamic NMR. In the inhibition of Pseudomona species lipase by 2,2'-bis-(N-substituted carbamoylmethyl)biphenyls (1-8), the logarithms of bi-molecular rate constants are multiply correlated with both the Taft substituent constant sigma* and E-s(D).
