IR Spectroscopy Basics
Infrared (IR) spectroscopy is a powerful analytical technique used to identify and characterize organic compounds. It involves the absorption of infrared radiation by molecules, causing the excitation of vibrational modes within the molecule. The frequency of the absorbed radiation corresponds to the energy difference between the vibrational energy levels of the molecule.
There are two main types of IR spectroscopy:
- Transmission IR spectroscopy:In this technique, the sample is placed between an infrared source and a detector. The infrared radiation is passed through the sample, and the amount of radiation absorbed is measured.
- Attenuated total reflectance (ATR) IR spectroscopy:In this technique, the sample is placed on a crystal that is in contact with an infrared beam. The infrared radiation is reflected off the crystal, and the amount of radiation absorbed by the sample is measured.
IR spectroscopy offers several advantages, including:
- High sensitivity
- Non-destructive
- Can be used to identify both functional groups and specific compounds
However, IR spectroscopy also has some disadvantages, including:
- Can be affected by water
- Can be difficult to interpret spectra
