Abstract: We show that the reflection coefficients in the quantum theory of the Liouville model calculated in the bootstrap and Hamiltonian approaches differ from each other by a phase factor and simply yield different normalizations of vertex operators.

Keywords: Liouvile quantum model, conformal bootstrap, conformal field theory.
