Experimental aspects in acquisition of wide bandwidth solid-state MAS NMR spectra of low-γ nuclei with different opportunities on two commercial NMR spectrometers

► Wideband MAS NMR spectra of low-γ nuclei on Varian and Bruker NMR spectrometers. ► Experimental and simulated 14N MAS NMR spectra of glycine. ► Electronic measurements and simulations of circuitries for two different preamplifiers. ► Different opportunities for wideband MAS NMR spectra of low-γ nuclei.
