WebDifferent functional groups give different stretching frequencies, which allow the identification of the functional groups present. As shown in this experiment, IR spectroscopy is a useful tool for the organic chemist to identify and characterize a molecule. In addition to organic chemistry, IR spectroscopy has useful applications in other areas. WebIn this context we have examined the suitability of the two techniques (KBr disc and Nujol mull) for IR spectral analyses to identify the antibiotic CFN in solid state. The results of …
Nujol is a brand of mineral oil by Plough Inc., cas number 8012-95-1, and density 0.838 g/mL at 25 °C, used in infrared spectroscopy. It is a heavy paraffin oil so it is chemically inert and has a relatively uncomplicated IR spectrum, with major peaks between 2950-2800, 1465-1450, and 1380–1300 cm . The empirical formula of Nujol is hard to determine exactly because it is a mixture but it is essentially the alkane formula C nH (2n + 2) where n is very large. WebNujol weist ein relativ einfaches Absorptionsspektrum im Infraroten auf. Seine Banden liegen zwischen 2950 und 2750 (s), 1465–1450 (m), 1380–1370 (m) und 620 (w) cm −1 ( Wellenzahlen ), die durch CH 2 - und CH 3 -Schwingungen verursacht werden. Die Banden überlagern meist nicht die charakteristischen Banden der Prüfsubstanz.
