INFRARED IR MATERIAL NO FURTHER A MYSTERY

A molecule can vibrate in numerous ways, and each way is termed a "vibrational mode". If a molecule has N atoms, linear molecules have 3N-five levels of vibrational modes Whilst nonlinear molecules have 3N-6 levels of vibrational modes.A necessary condition for optical elements to work with infrared mild is the fact that transparency (i.e., propaga
