Infrared Spectroscopy (IR) is very useful for determining the functional groups present in an organic molecule. For each of the spectra below, complete the following: • Build the molecule in Spartan and describe the motion of the molecule at each key absorption frequency • Identify key absorption frequencies in the spectrum and identify the type of stretch/bend/wag/etc. (i.e. O-H) • Match the spectra from the provided structures • Identify the main functional groups in the molecule OH A B F D E H OH NH2 J Transmitance 1.1 1.0 0.9 99 0.8 0.7 0.6 0.5 0.4 0.3 0.2 22 0.1 3500 3000 2500 m 2000 1500 1000 500 Wavenumbers (cm-1)
