LITTLE KNOWN FACTS ABOUT IR MATERIAL.

A molecule can vibrate in numerous ways, and each way is called a "vibrational method". If a molecule has N atoms, linear molecules have 3N-five levels of vibrational modes whereas nonlinear molecules have 3N-6 levels of vibrational modes.The penetration depth in the evanescent wave throughout the sample is about the get of 1µm.
