Adiabatic rotational splittings and Berry's phase in nuclear quadrupole resonance.
TLDR
Sample rotation is shown to induce frequency splittings in nuclear-quadrupole-resonance spectra, interpreted both as a manifestation of Berry's phase and as a result of a fictitious magnetic field, associated with a rotating-frame transformation.Abstract:
Sample rotation is shown to induce frequency splittings in nuclear-quadrupole-resonance spectra. The splittings are interpreted both as a manifestation of Berry's phase, associated with an adiabatically changing Hamiltonian, and as a result of a fictitious magnetic field, associated with a rotating-frame transformation. Real and fictitious fields are contrasted. Related effects are predicted in other magnetic resonance experiments that involve sample rotation.read more

The Geometrical Phase in the PEANUT Experiments for the NQR Spectroscopy for the Spins I = 3/2
TL;DR: In this paper, the results of a non-cyclic geometrical phase of the 35Cl nuclear quadrupole resonance (NQR) signals are presented, caused by the character of nuclear magnetization trajectory under radio-frequency excitation by means of PEANUT sequence for powdered samples.
