solid-state quadrupolar Carr-Purcell-Meiboom-Gill spectrum magic-angle spinning quadrupolar Carr-Purcell-Meiboom-Gill spectrum QCPMG-MAS spectra https://orcid.org/0000-0001-5985-7429 A plot of the nuclear magnetic resonance frequency vs. intensity composed of a series of peaks (separated by the reciprocal of a user-defined time delay in a QCPMG pulse sequence) which describe the envelope of the full, static spectrum. Line broadening has been averaged to zero by spinning the solid sample very rapidly at the magic angle (54.74° with respect to the direction of the magnetic field).
