4. Recording method for 87Sr NMR spectra

4.1 Characteristics of the 87Sr core

Strontium is a member of the alkaline earth element family (Z = 38). We will return to some of this element's chemical and biochemical properties in the next paragraph. The main NMR characteristics of ⁸⁷ Sr are presented in Table 1 . At first glance, this is clearly a difficult nucleus to study. Indeed, its natural abundance is very moderate (~ 7.0%) and the value of γ ( ⁸⁷ Sr) is particularly low. At present, whatever magnetic field B _...
