Abstract

Ab initio MO-SCF wave functions are derived for H2S for different bond angles by using a double-zeta type set of gaussian s and p orbitals. The predicted equilibrium bond angle is 95.5°. The computed value of the total electronic energy is expected to be near the Hartree-Fock limit for the molecule. The predicted value of the dipole moment does not show significant improvement with respect to similar computations not including polarisation functions.

Zusammenfassung

Ab inittio-Funktionen aus Doppel-ζ-Gaussfunktionen werden für H2S bei verschiedenen Valenzwinkeln angegeben. Die tiefste Energie (95.5°) dürfte nahe beim Hartree-Fock-Wert liegen. Die Einführung von polarisierenden Funktionen liefert hinsichtlich des Dipolmomentes keine Verbesserung.

Résumé

Des calculs non empiriques pour plusieurs valeurs de l'angle de liaison ont été effectués pour H2S avec une base étendue de fonctions gaussiennes s et p. L'angle d'équilibre prévu est de 95.5°. L'énergie électronique totale est estimée très proche de la limite Hartree-Fock pour la molécule. La valeur du moment dipolaire calculé est pareille à celle qui a été trouvée par d'autres calculs n'incluant pas des fonctions de polarisation.
