The effect of dipole-dipole cross correlations on the net nuclear Overhauser effect (NOE) has been analyzed here for realistic systems by extending the three-spin calculations to four and five spins in order to account for additional cross correlations and spin diffusion. These have been compared wi

## Abstract The expressions for the functions of spectral density at different orientations of the components of the internuclear vector with respect to the chain backbone, the frequency dependences of the spinβlattice relaxation time of ^13^C nuclei (__T__~1C~) and the values of the nuclear Overha
High-resolution 13C NMR spectra of 15 samples of uncomplexed and metalcomplexed tetranactin and nonactin were recorded in the solid state, revealing characteristic displacements of peaks due to complex formation and the effect of crystalline packing on the 13C chemical shifts and spidattice relaxati
