Abstract
Effective operators are relevant tools in solving any physical problem involving degenerate eigenstates which may be split by a perturbation. The basic method, the Van Vleck-transformation, is reviewed in Section 1.1, whereas the remaining part of the paper is concerned exclusively with applications to vibration-rotation spectroscopy.
