A method for broadening the Hartmann-Hahn matching condition for cross polarization under magic angle spinning is presented. Variabkfkctive-field cross polarization (VEFCP) employs different effective radio-frequency (rf ) fields on the 'H channel during mixing, while the "C rffield remains constant
## Abstract A novel selective homonuclear HartmannβHahn transfer method for in vivo spectral editing is proposed and applied to measurements of Ξ³βaminobutyric acid (GABA) in the human brain at 3 T. The proposed method utilizes a new concept for in vivo spectral editing, the spectral selectivity of
