Abstract
Some fundamental properties are found for the singlet ground state and lowest triplet excited state in the spin s = 1 linear chain Heisenber g antiferromagnet with arbitrary chain length. The influence of the an isotropic term on these states is evaluated by spin polarization on th e site of the chain. The energy levels based on these analyses are in good agreement with the experimental spectroscopes.
