Abstract : The internal axis method is extended to treat the effects of internal rotation in the microwave spectra of molecules with several internal symmetric tops. As a first approximation the method ignores all top-top coupling and assumes that the potential for each top is purely sinusoidal. An arbitrary number of tops is first considered and then specialization is made to the most important case, the ground state of a molecule with two equivalent tops, which turns out to be extraordinarily simple. Finally, the refinement of the method which takes the top-top coupling into account is considered. (Author)
