Fluctuation effects in nematic-type phases in quantum systems of spin 1 and 3/2 are examined. The analogue of the Mermin-Wagner theorem is formulated and the perturbation theory is shown to be logarithmically divergent under certain conditions. The low-energy excitations depend on the parity of 2S.
