Recording method for 87Sr NMR spectra
Ultra-wide line solid state NMR of quadrupolar nuclei: example of strontium-87

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 ⁸⁷Sr 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 (⁸⁷Sr) is particularly low. At present, whatever magnetic field B₀ is considered, ν₀ (⁸⁷Sr) remains below 45 MHz! An essential...
