INTRODUCTION
Like all spectroscopic methods, infrared spectroscopy involves the exchange of energy between a molecule and electromagnetic radiation.
In the near infrared (12,500 to 4,000 cm -1 ) and mid infrared (4,000 to 650 cm -1 ), transitions between vibrational energy levels are observed and quantified.
In the far infrared (up to 10 cm -1 ), transitions between rotational energy levels are also quantified.
In organic chemistry, the mid-infrared is most often exploited, but the region between 650 and 250 cm -1 is very useful in coordination chemistry.
