By mapping the triangular antiferromagnet, the Villain model and the Union-Jack model on the quantumXY-chain we show a simple way to obtain the exponent η=1/2 for the decay of the spin-correlation function at the frustration points of these models. A similar procedure for the Baxter model leads to non-universal values of η.
