Using the quantum transfer-matrix method we have calculated the spin correlationfunctions of the S= 3 /2 XXZ chain and examined the temperature dependence of themass (:the inverse of the correlation length), susceptibility 7'(Q) and the magneticstructure factor S"(Q). The result shows that the mass vanishes at T=O for the planarand isotropic cases ( - 1 @A 5 l) in agreement wi1.h the theoretical prediction. At alow temperature the peak of ,5'(0) at Q=n has been observed to persist even in theferromagnetic region (0<J<0.8). The susceptibility z'(0=O) at T=0 has been ob-tained with use of the extrapolation. The critical indices have been also examined.
