Infrared and NMR Spectroscopies:
Infrared spectroscopy (IR) involves the interaction of infrared radiation with matter. Functional groups will behave (vibrate, stretch, flex, wiggle, basically move around) at different ranges on a spectrum based on the type of functional group. This can be used to identify and study chemical substances.
The width and location of the peak in an IR is indicative of what functional group caused it. Alcohol and carboxylic acid peaks are very broad verses carbonyl peaks which are very narrow and sharp. Substituted benzene rings have peaks that correspond to the substitution pattern (, , , , ) in the fingerprint and overtone regions of the IR.
In nuclear magnetic resonance spectroscopy (NMR), the hydrogen signals split based on dissimilar hydrogens on adjacent atoms. The magnitude of the peaks (area under the peak) tells us how many hydrogens are being split. The number of adjacent hydrogens determines the splitting. Zero dissimilar adjacent hydrogens gives a singlet, one dissimilar adjacent hydrogen gives a doublet, two dissimilar adjacent hydrogens gives a triplet, and so on and so forth. The shift (or delta or peak location) is based on the number and type of electronegative group(s) present, such as carbonyls, alcohols, esters, halogens, etc. Also, shifts will still occur when the hydrogen(s) is(are) bonded to non-carbon atoms, such as N or O.
Another type of NMR is
13 13
C-NMR where the signals are generated by the carbons in the molecule with similar splitting possibilities as in proton-NMR.
