phase shift

in nuclear magnetic resonance, the change in phase caused by movement of the spins, which can be used to show fluid flow.

phase shift

An alteration in the time relationship between the peaks (or troughs) of two different periodic functions. Thus, two circadian rhythms may suffer a phase shift as in jet lag.
