Schwingungen von Molekülen im Kristallgitter - Melamin mit Wasserstoffbrücken

Translations- und Torsionsschwingungen der Moleküle. Am Beispiel des Melamins werden die elastischen Eigenschaften der zwischenmolekularen Wasserstoffbrücken-Bindungen demonstriert. Anhand der thermisch bei 60 und 300 K angeregten Gitterschwingungen wird verdeutlicht, daß sie der mechanische Speicher der spezifischen Wärme des Melamin-Kristalls sind.
