• We consider the issue of chiral ordering in spin chains for an arbitrary value of the spins S. By use of bosonization according to a scheme developped by H.-J. Schulz, we obtain a phase diagram of the chain with XY exchange couplings between the nearest and the next-to-nearest neighbors. We obtain a satisfactory picture including a so-called chiral spin nematic phase which is gapless, has long-range chiral order and incommensurate spin correlations. We perform a stability analysis of this phase and point out that this analysis is in conflict with existing DMRG results that show a difference between integer and half-integer spin cases.
