Nuclear magnetic resonance reorientational correlation functions: the odd-valued spectral components

Practical consequences attributable to nonvanishing imaginary spectral components of the second rank spherical harmonic angular correlation function are described in detail. This analysis presumes the absence of macroscopic spatial anisotropies. Modulation frequency, anisotropy, and cross correlation of interaction between a nuclear spin and the extranuclear environment are considered. These findings permit a critical assessment of the second-order ultrafine dynamic frequency shift in the nuclear magnetic resonance experiment.
