What Does CPMAS Stand For?

CPMAS stands for Cross Polarization Magic Angle Spinning C 13 NMR

CPMAS, or Cross Polarization Magic Angle Spinning C-13 NMR, is a solid-state nuclear magnetic resonance technique used to enhance the signal of carbon-13 nuclei in samples with low natural abundance. By utilizing cross polarization, it efficiently transfers polarization from abundant protons to carbon-13, resulting in improved sensitivity. The magic angle spinning technique minimizes the effects of anisotropic interactions, providing high-resolution spectral data. CPMAS is widely applied in materials science, chemistry, and biochemistry for studying complex organic materials, polymers, and biomolecules.
