WebSep 17, 2024 · • Infrared radiations refers broadly to that part of electromagnetic spectrum between visible & microwave region. • It is based on the absorption spectroscopy in which molecular vibration is observed due to absorption of IR radiation. • It measures the bond vibration frequencies in a molecule. WebVideo transcript. We've already looked at a carbon-hydrogen bond, and in the last video, we actually calculated an approximate wavenumber for where we would expect the signal for a carbon-hydrogen bond stretch to appear on our IR spectrum. And we got a value of a little bit over 3000 wavenumbers.

WebIR SPECTROSCOPY Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used … See more Infrared spectroscopy exploits the fact that molecules absorb frequencies that are characteristic of their structure. These absorptions occur at resonant frequencies, i.e. the frequency of the absorbed radiation matches … See more IR spectroscopy is often used to identify structures because functional groups give rise to characteristic bands both in terms of intensity and position (frequency). The positions of these … See more Infrared spectroscopy is a simple and reliable technique widely used in both organic and inorganic chemistry, in research and industry.
