What Is the IR Spectrum of Cyclohexane?

By Staff WriterLast Updated March 31, 2020

The IR spectra of cyclohexane includes a strong intensity of 2960-2850 of stretching absorption and a variable intensity of 1470-1350 of scissoring and bending absorption. The molecular formula for cyclohexane is C6H12, and the spectrum corresponds to the functional class of bonds in alkanes, CH2.

Determining IR spectrum, also known as infrared spectra, involves using known frequencies of certain types of bonds and then correlating these known frequencies with absorption bands in the spectrum of an unknown compound. Absorption bands may be described by their intensity, shape and position in the spectrum. Common groups with known absorption frequencies include alkanes, alkenes, alcohols and amines.
