Abstract: This paper deals with derivations on algebras that are generated by a maximal abelian selfadjoint algebra of operators $ \mathcal{A}$ on a Hilbert space and a group of unitary operators acting on it. A necessary and sufficient condition for such a derivation to be implemented by an operator affiliated with $ \mathcal{A}$ is given. The results are related to the study of derivations on a certain class of irreducible triangular algebras.
