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.
