Hammett Parameter and Molecular-Modeling Correlations of Substituent Effects on Esterification Kinetics

Journal of Chemical Education, 2010
The effect of substituents on the rate of reactions is taught extensively throughout organic chemistry. The Hammett equation is useful in quantifying this dependence; however, there are relatively few experiments that investigate this relationship.

Correlation of nmr Chemical Shifts with Hammett σ Values and Analogous Parameters

1978
This chapter is devoted to an examination of the correlation of nmr chemical shifts with Hammett’s structure-reactivity parameters and analogous parameters developed by others. Correlation analysis in nmr spectroscopy as a whole is, of course, a much wider field, involving as it does, exploration of the interrelationships between nmr data and the ...
