Quantitative NMR Interpretation without Reference J. Anal. Methods Chem. (IF 2.6) Pub Date : 2022-11-10 Priscila Ivo Rubim de Santana, Joyce Sobreiro Francisco Diz de Almeida, Tanos Celmar Costa França, Jochen Junker
As has been documented numerous times over the years, nuclear magnetic resonance (NMR) experiments are intrinsically quantitative. Still, quantitative NMR methods have not been widely adopted or largely introduced into pharmacopoeias. Here, we describe the quantitative interpretation of the 1D proton NMR experiment using only absolute signal intensities with the variation of common experimental parameters
