PPT-Infrared Spectroscopy Infrared absorption spectra

are due to changes in vibration energy accompanied by changes in rotation energy broadly speaking the range in the electromagnetic spectrum that extends from 08 200 µm is referred to as the infrared region .

The difference in energy between molecular bonding, non-bonding and anti-bonding orbitals ranges from 125-650 kJ/mole. This energy corresponds to EM radiation in the ultraviolet (UV) region, 100-350 nm, and visible (VIS) regions 350-700 nm of the spectrum. Ottillia Ni. Mentor: Dr. . Kristan. Corwin. August . 5, 2016.
