Hyperfine coupling in non-rigid molecular systems with several equivalent nuclei is very interesting because of the averaging due to the large amplitude motion(s). For instance, in the cases of the non-rigid (D O) and (C D ) dimers, the molecule behaves as if quadrupole coupling was identical for all four deuterium atoms. This result, only valid for nondegenerate tunneling levels, disagrees ind...

The observed solar oscillation spectrum is influenced by internal perturbations such as flows and structural asphericities. These features induce splitting of characteristic frequencies distort the resonant-mode eigenfunctions. Global axisymmertric flow -- differential rotation a very prominent perturbation. Tightly constrained profiles function latitude radius are products established heliosei...

Normal-mode helioseismic data analysis uses observed solar oscillation spectra to infer perturbations in the interior due global and local-scale flows structural asphericity. Differential rotation, dominant global-scale axisymmetric perturbation, has been tightly constrained primarily using measurements of frequency splittings via "$a$-coefficients". However, frequency-splitting formalism invok...
