MATPASS/CPMG: A sensitivity enhanced magic-angle spinning sideband separation experiment for disordered solids

► An efficient spinning sideband separation allows for isotropic spectra of disordered solids. ► CPMG multiple echo acquisition enhances sensitivity by an order of magnitude. ► MAT/CPMG protocol avoids √2 signal loss of PASS/CPMG. ► 77Se MATPASS/CPMG experiment allows for isotropic shift and CSA measurement of GeSe4 glass.
