  The effect of Gaussian fluctuations of nanopores filled with a gas of
spin-carrying molecules ($s=1/2$) on the multiple quantum (MQ) NMR dynamics is
investigated at different variances and correlation times of the fluctuations.
We show that the fluctuations smooth out the evolution of MQ NMR coherence
intensities which rapidly oscillate as functions of time in the absence of
fluctuations. The growth and decay of the MQ coherence clusters in the
fluctuating nanopore are also investigated.
