Abstract
Using a simple quantum model we calculate static correlations for the random S = ½ Heisenberg antiferromagnets. The correlations decay exponentially with distance. In addition the second moment of a two-spin correlation function was evaluated. No agreement with experiment could be obtained when we tried to extract the correlation time of this correlation function from its second moment.
