WebThe Importance of Using the Correct Material. Since infrared light is comprised of longer wavelengths than visible light, the two regions behave differently when propagating through the same optical medium. Some materials can be used for either IR or visible applications, most notably fused silica, BK7 and sapphire; however, the performance of ...
WebFor example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present. reformat seagate external hard drive windowsWebOn an IR spectrum, certain “peaks” (or rather “valleys”) corresponds to an important resonance frequency of a bond found in your compound. The x-axis is displayed in units of inverse centimeters (cm -1 ), also called “wavenumbers”, which indicates the inverse of the resonance frequency.
