Description A Monte Carlo sampling technique based on 2 x 2 rotations of the Heisenberg spin-1 Hamiltonian containing both anisotropic and next-nearest-neighbour (NNN) terMS has been attempted. Closed rings of six, eight, 10 and 12 spin-1 sites have been studied and the ground and the first excited states have been obtained. The validity of the procedure has also been tested using the spin correlation function for the ground state.
