| Abstract: | Abstract A series of phosphoric amidodiesters, diamidoesters and triamides was prepared and their 31P and15 N NMR spectra were recorded in order to evaluate the major structural factors that determine the chemical shifts and coupling contants values. Considering the equation expressing the structural effects on shielding1]. |
