N2 - Exact expectation values of the fields eaφ in the Bullough-Dodd model are derived by adopting the "reflection relations" which involve the reflection S-matrix of the Liouville theory, as well as a special analyticity assumption. Using this result we propose explicit expressions for expectation values of all primary operators in the c < 1 minimal CFT perturbed by the operator Φ1,2 or Φ2,1. Some results concerning the Φ1,5 perturbed minimal models are also presented.
