Current-voltage characteristics, voltage oscillations and NMR on the same Rb0.3MoO3 crystal at 77 K are presented. The 1 2, - 1 2 transition at ν0=80 MHz of 87Rb nuclei broadened by the CDW modulation is motionallu narrowed for bias currents exceeding threshold for non-linear conduction. Calculation of the lineshapes, assuming a partial depinning of the sample, leads to excellent agreement with experiment. An estimate of the ratio of the average current density and voltage oscillation frequency in the depinned region agrees roughly with phenomenological models. A CDW phase correlation time of single domain is deduced to be τ=200 μS.
