Anisotropic interactions between nuclei, which are usually averaged by Brownian motion in liquid samples, cause significant line broadening in solid state NMR, but can be averaged to zero by spinning the sample very rapidly at the magic angle (54.74° with respect to the direction of the magnetic field). Cross polarisation is used to enhance the signal from weakly coupled nuclei such as 109Ag nuclei. 109Ag cross polarization magic angle spinning nuclear magnetic resonance spectroscopy 2009-09-15T05:21:53Z https://orcid.org/0000-0001-5985-7429 109Ag CPMAS NMR 109Ag CP/MAS NMR 109Ag cross-polarization magic angle spinning 109Ag cross-polarization magic angle spinning nuclear magnetic resonance spectroscopy 109Ag CPMAS 109Ag cross polarisation magic angle spinning nuclear magnetic resonance spectroscopy CHMO:0002375 109Ag CP-MAS NMR silver-109 cross-polarisation magic angle spinning
