✦ Synopsis

We present a tensorial formalism adapted to the study of the ( (n 000) ) rovibrational stretching states of spherical tops in the local mode limit. A local symmetrized rovibrational basis is built to take explicitly into account the fact that. in these states, the local symmetry is (C_{3 v}) rather than (T_{d}). Likewise, we introduce local rovibrational operators to build an effective Hamiltonian for these states. We then test our model by fitting the energy levels of ({ }^{28} \mathrm{SiH}_{4}) for (3 \leqslant n \leqslant 5). Cc 1995 Academic Press, Inc.
