Density-based methods measurement vector

In CH2 groups dipolar cross-correlation spectral densities describe mutual motions of CH vectors and can be used to derive motion characteristics. These parameters are often difficult to measure due to low sensitivity of the previously proposed experiments. A simple sensitive method to derive CH2 dipolar cross-correlation densities was described by Idiyatullin et The method is based on the measurement of the relaxation rates with and without crossrelaxation contribution. The sequence starts with the evolution of the longitudinal Cz magnetisation. Due to the cross-correlated relaxation this...
