Abstract

A tensorial formalism adapted to the case of $X 2 Y 4$ asymmetric $m o l e c u l e s a$ with $D 2 h$ symmetry has been developed in the same way as in the previous works on $X Y 4 b (T d)$ and $X Y 6 c (O h)$ spherical tops, $X Y 5 Z (C 4 v)$ symmetric $t o p s d, e$ or $X Y 2 Z 2 (C 2 v)$ asymmetric $t o p s f$ . We have then constructed a Stark Hamiltonian using the same principle. This model allows the calculation of Stark shifts and splittings in the spectra of $D 2 h$ molecules. Preliminary predictions will be shown for some rovibrational bands of the $C 2 H 4$ molecule.
