Vibrational spectra are of two types [1], infrared and Raman, and arise from two different types of energy exchanges between the molecules under study and electro-magnetic radiation. In infrared spectroscopy, a vibrational transition that involves a change in dipole moment results in absorption of an infrared photon. The energy of

Infrared absorption spectra usually cover the range 200-4000 cm-1 or 50-2.5 micrometers (microns). . The other important aspect to IR and Raman spectroscopy is that the time scale of the measurement amounts to the time it takes for a vibration ( 0.1 psec). Even rapidly isomerizing species show distinct vibrational spectra in contrast to slower

Spectroscopy is a powerful non-contact technique for quickly recognizing and characterizing physical materials through the variations in absorption or emission of different wavelengths of light. Spectroscopy can be performed using visible, infrared (IR), or ultraviolet (UV) wavelengths.
