Assignment of the 1H and 13C nuclear magnetic resonance spectra of norethisterone using two-dimensional nuclear magnetic resonance spectroscopy

Abstract

The information obtained from 2D J-resolved and 2D spin-echo-correlated spectroscopy at 500 MHz allows the complete assignment of the 1H n.m.r. spectrum of norethisterone. In turn, the 1H n.m.r. assignment readily leads to the assignment of the 13C n.m.r. spectrum of this compound by means of a two-dimensional hetero-shift correlation experiment.
