Signs of frequencies and phases in NMR: the role of radiofrequency mixing.
This article analyzes the influence of the radiofrequency mixing scheme on the sign of phase shifts experienced by the nuclear spins. It is an addendum to a previous article on the signs of phases and frequencies in NMR (M. H. Levitt, J. Magn. Reson. 126, 164 (1997)).
