We present here a model calculation of the spin-echo gradient nuclear magnetic resonance signal of a Brownian particle diffusing in a confined environment, described by a harmonic potential well. The general expression reduces to characteristic scaling laws in limiting cases: long and short pulses, comparative to the spin-echo duration, and long, intermediate, and short durations of the spin phase reversal cycle, comparative to the internal system characteristic times scales. Spin-echo measurements in these limits enable one to detect independently the particle's mass, viscous drag, and the confining potential strength. © 1995 American Institute of Physics.
