WebInfrared spectroscopy can be used to identify certain functional groups in an organic compound. Infrared radiation causes parts of a molecule to vibrate. The wavelengths … WebMar 16, 2024 · Infrared radiation is the proper energy to excite vibrations in molecules. The IR spectrum consists of near (4,000-12,800 cm -1 ), mid (200-4,000 cm -1) and far (10-200 cm -1) regions. The mid-IR region is most commonly used for analysis purposes. Vibrational excitations correspond to changes in the internuclear distances within molecules.
WebInfrared spectroscopy is a technique that probes the vibrations within a material. It is complementary to Raman spectroscopy (Section 11.2.2) in that many Raman active vibrational modes are not detectable in infrared spectroscopy and vice versa. It can identify functional groups which have characteristic vibrational energies and can thus be ... WebEvery mass spectrometer consists of at least these three components: Ionization Source Mass Analyzer Ion Detection System 1. The Ionization Source Molecules are converted to gas-phase ions so that they can be moved about and manipulated by external electric and magnetic fields.
