We review the numerical diagonalization study on the spin flop in 1D higher-S quantum spin chains in the presence of the coupling or single-ion anisotropy. The result suggested that the transition can be second-order for the system which is mapped onto the S = 1/2 XXZ chain. A new result for the S = 1/2 spin ladder is also presented.
