Abstract
Integrable deformations of two affine Toda field theories based on BCn and C-(1)(n) non-simply laced algebras are studied. The proof of quan tum integrability of the two theories is given and it is shown that th e two theories are dual, corresponding respectively to the weak and st rong coupling regimes of an intermediate theory. Perturbative calculat ions and the bootstrap principle permit the construction of the interm ediate quantum field theory which flows from the first to the second w ith the coupling constant.
