description | Low frequency polarized spectra were investigated from 300 to 30K; but, as accidental depolarization arises at low temperature, study was chiefly made at 300K. External vibrations have been assigned using group theory and the influence of hydrogen bonds on the motions of the molecular layers: Ag‐Bg librations at 41.6–64.8, 83.5–42.4 and 130cm−1, translations in‐plane at 79 and 94, out‐of‐plane at 144 cm−1, owing to layers. Some infrared bands have been observed and assigned.
Résumé. Les spectres polarisés de basse fréquence ont été étudiés de 300 à 30K; mais à cause d'une dépolarisation accidentelle apparaissant à basse température, ce travail a été principalement effectué à 300K. Les vibrations externes ont été attribuées à l'aide de la théorie des groupes et de l'influence des liaisons hydrogène sur les mouvements des couches moléculaires: librations Ag‐Bg à 41.6–64.8, 83.5–42.4 et 130 cm−1 translations parallèles aux couches à 79 et 94 cm−1, normales aux couches à 144 cm−1. Quelques bandes infrarouges ont été observées et attribuées. |
