So, the characteristic frequency of thermal motion is around 7E12 Hz at room temperature (300K), but from that information how can we conclude that the bonds are hard; they don't vibrate !!




The bond energy is related to which kind of molecules are involved in the bond itself (their polarity,...). all the molecular bonds undergo some kind of vibration (they can bend, stretch, rock,...) which peculiar frequency varies according to the type of bond and molecules involved.
