N2 - We derive simple semi-analytical expressions for the Stark energy levels of a general symmetric-top molecule placed in a uniform electric field of arbitrary strength. These are obtained by means of third-order perturbation theory following a suitable canonical transformation of the system Hamiltonian, which is conveniently written in terms of the generators of either of the Lie algebras 5(9(3) or 50(2, 1).
