Infrared (IR) and Nuclear Magnetic Resonance (NMR) are two spectroscopic techniques you've encountered in organic chemistry I, CHM2210. In organic chemistry laboratory, IR and NMR are common tools used to characterize a given product. Consider what you learned in CHM22110, and select the concepts that you feel confident about: Group of answer choices Assigning 1H NMR signals to a given molecule The theory behind NMR Identify splitting patterns I do not recall/understand much about NMR correlate the intensity of a 1H NMR signal to the number of protons The theory behind IR I do not recall/understand much about IR Assigning 13C NMR signals to a given molecule Identify functional groups based on IR absorptions Understanding (de)sheilding Deduce the structure of an unknown given its molecular formula, IR and NMR spectra
