• The theory of the resonating valence bond (RVB) for the antiferromagneticHeisenberg model of spin 1 / 2 proposed by Anderson is generalized by taking accountof singlet bonds connecting distant spins, and is solved exactly for the finite lattice. Itis shown that the RVB wave function is 'lot (total spin quantum number) = 0, and thatreplacing a part of singlet bonds by triplet bonds, eigenfunctions with 'lot = 1, 2, - =can be constructed. These are the new representation of eigenfunctions of theHeisen berg Hamiltonian.
