 Title: STARK EFFECT USING TENSORIAL FORMALISM IN THE $D_{2h}$ GROUP: APPLICATION TO THE $C_{2}H_{4}$ MOLECULE Creators: Raballand, W.; Rotger, M.; Boudon, V.; Loete, M. Issue Date: 2004 Abstract: A tensorial formalism adapted to the case of $X_{2}Y_{4}$ asymmetric $molecules^{a}$ with $D_{2h}$ symmetry has been developed in the same way as in the previous works on $XY_{4}{^{b}}(T_{d})$ and $XY_{6}{^{c}}(O_{h})$ spherical tops, $XY_{5}Z (C_{4v})$ symmetric $tops^{d,e}$ or $XY_{2}Z_{2} (C_{2v})$ asymmetric $tops^{f}$. 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 $D_{2h}$ molecules. Preliminary predictions will be shown for some rovibrational bands of the $C_{2}H_{4}$ molecule. URI: http://hdl.handle.net/1811/21200 Other Identifiers: 2004-MH-03
