Abstract
The dimer state for the spin-1/2 quantum Heisenberg antiferromagnet is studied using the theory of resonating valence bond. The present theo ry is systematic and much more simple than the other theories. We obta in two important theorems. By use of them we can get the dimer eigen s tate in the linear chain, ladder, square and simple cubic lattices by the unified way. If the relations between exchange integrals are satis fied, the obtained dimer eigen state is the ground state.
