What type of reaction mechanism is operative in the conversion of 2-methyl-2-butanol into 2-chloro-2-methylbutane? IR absorption spectrum is called fingerprinting, and is one method of determining molecular structure, particularly certain reactive groups in organic (carbon-containing) molecules which are termed functional groups. in this collection were collected can be found NIST Standard Reference As you can see, the three spectra look very similar in the area above the fingerprint region (above 1500 cm-1). ited, IR spectra were first recorded for ice thicknesses up to 4 μm and resolutions up to 0.5 cm−1.
