We present a dielectric study on the dynamics of supercooled glycerol during
crystallization. We explore the transformation into a solid phase in real time
by monitoring the temporal evolution of the amplitude of the dielectric signal.
Neither the initial nucleation or the crystal growth influence the liquid
dynamics visibly. For one of the samples studied, a tiny fraction of glycerol
remained in the disordered state after the end of the transition. We examined
the nature of the alpha relaxation in this frustrated crystal and find that it
is virtually identical to the bulk dynamics. In addition to that, we have found
no evidence that supercooled glycerol transforms into a peculiar phase where
either a new solid amorphous state or nano-crystals dispersed in a liquid
matrix are formed.Comment: 7 pages, 7 figure
