1. Theoretical background
The principle behind the nuclear magnetic resonance spectrometry method is briefly outlined here.
1.1 Principle
-
Gyromagnetic ratio
The nuclei of atoms, with the exception of those whose atomic number and mass number are simultaneously even, have a non-zero, half-integer or integer spin quantum number I. In this case, they have a spin angular momentum I, with modulus: 1. They therefore have a spin angular momentum I, of modulus :
