Abstract

A theoretical investigation of the vibrational motion of a free nine-atomic tetrahedral molecule is given using Wilson's. FG-matrix method. By going to the limit of infinite mass of the outermost atoms, the vibrational frequences of a bound five-atomic tetrahedral molecule are obtained. This limiting case is also alternatively treated by the explicit consideration of the hindered translational and rotational motions. Such a model would probably approximate the state of affairs for amorphous substances with a tetrahedral basic unit.

Zusammenfassung

Die Schwingungen eines freien, neunatomigen, tetraedrischen Moleküls werden analysiert. Indem man die Massen der äußersten Atome unendlich werden läßt, erhält man die Schwingungsfrequenzen eines gebundenen, fünfatomigen tetraedrischen Moleküls. Dieser Fall wurde auch direkt unter Berücksichtigung der Behinderung der Bewegungen behandelt. Dieses Modell könnte zur Beschreibung amorpher Substanzen aus tetraedrischen Grundeinheiten dienen.

Résumé

Etude théorique du mouvement vibratoire d'une molécule libre tétraédrique à neuf atomes au moyen de la méthode de la matrice FG de Wilson. En passant à la limite de masse infinie des atomes périphériques, les fréquences vibrationnelles d'une molécule liée tétraédrique à cinq atomes sont obtenues. Ce cas limite est aussi traité par la considération explicité des mouvements de rotation et de translation non libres. Un tel modéle constitue probablement une approximation pour les substances amorphes à unité de base tétraédrique.
