Title: Study of the rovibrational intensities of tetrahedral molecules and prediction of the pentad poliade of {sup 12}CD{sub 4}

The use of tensor models adapted to tetrahedral molecules such CH{sub 4}, SiH{sub 4}, G{sub e}H{sub 4}... that use mathematical tools (group theory, irreducible tensor operators) and the characteristics of symmetrical molecules, gives good results. Starting from an experimental spectrum, we can calculate some parameters of the Hamiltonian and consequently the energy levels. Once the line positions are determined, we calculate the parameters of the dipole moment of these molecules and consequently the rovibrational intensities. Both software STDS and SPVIEW, we determined the parameters of the Hamiltonian and those of the dipole moment.
