INFRARED IR MATERIAL NO FURTHER A MYSTERY

A molecule can vibrate in some ways, and every way is named a "vibrational manner". If a molecule has N atoms, linear molecules have 3N-5 degrees of vibrational modes whereas nonlinear molecules have 3N-6 levels of vibrational modes.Some are created as laser line optics for precise wavelengths, while some function in vast wavelength ranges.
