Like other amines, pyridines and anilines readily form hetero complexes, and this has provided a means of studying the influence of substituent electronegativity on vanadium chemical shifts. Hammett plots for a number of anilines and pyridines revealed a linear relationship between substituent electronegativity and chemical shifts and showed, for both classes of ligands, that51V chemical shifts became more... [Pg.101]

Electronegativity and chemical shift are related in the following way the presence of an electronegative atom or group reduces electron density on atoms bonded to it and therefore the shielding. This effect deshields nearby nuclei and causes them to resonate farther downfield (i.e., with a larger chemical shift). [Pg.556]
