Abstract
The group theoretic method is extended to include fields with a background charge. This formalism is used to compute the tree level scattering for strings. The scattering amplitudes involve Ising model correlation functions. A detailed study of the four tachyon amplitude shows that the string must possess additional states in its spectrum associated with intercept and the energy operator of the Ising model.
