Because infrared spectroscopy is naturally diffraction-limited in the information it can obtain from any given sample, new methods have been devised to perform IR probing on the nanoscale. Presentation Summary :IR Spectroscopy is used for qualitative identification of organic and inorganic compounds. This was accomplished by the use of a prism or grating. • Mid-IR spectroscopy makes use of fundamental vibrations • Near-IR spectroscopy uses Overtones and Combination Bands • Overtones and Combination Bands are types of vibrations related to the fundamental vibrations seen in the Mid-IR 12000 cm 9000 cm-1 6000 cm-1 3000 cm-1 3rd Overtone 2nd Overtone 1st Overtone Fundamental Vibration And they’re ready for you to use in your PowerPoint presentations the moment you need them.
