Source: – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 41e3e8-NWJkY The IR spectrum of a compound can provide important information about its chemical nature and molecular structure. Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than visible light Infrared Spectroscopy is the analysis of infrared light interacting with a molecule. In addition, the use of synchrotron radiation for infrared spectroscopy has been shown to be particularly useful for small samples such as those in high-pressure cells (Figure 3(a)). Infrared (IR) spectroscopy or vibrational spectroscopy is an analytical technique that takes advantage of the vibrational transitions of a molecule. Vibrational CD (VCD) spectroscopy uses IR light to determine 3D structures of short peptides, nucleic acids, and carbohydrates. As shown in Figure 1, the sector of the spectrum extending from the nearly 10 −3 m (microwave) to the 780 nm (visible) wavelength range is labeled as the infrared (IR) region. ...
