The HNMR Spectrum in an OH Group: Exploring
Hydrogen Nuclear Magnet Resonance spectrum (HNMR), of an OH-group is powerful for analysing the structure of a molecular. The HNMR spectrum of an OH group, composed of hydrogen atoms and oxygen, can be resonant in the presence of a magnetic field. An HNMR spectrum from an OH group is a rich source of information regarding the structure of the molecules, including how many and what types of hydrogen are present as well as bond lengths and angles and chemical bonds. The spectrum of an OH group that is exposed to HNMR will often contain multiple distinct signals (Frey 2019,). Number of hydrogen atoms in a molecule will determine the number of signals it generates. Each hydrogen atom generates a signal within the spectrum. This results in unique signals for every hydrogen atom. If a molecule has three hydrogen atoms then it will produce three signals in the spectrum (Frey 2019,). But, it is possible for a molecule to generate one spectrum signal if they contain identical hydrogen atoms. Because the hydrogen atoms can be compared, the signal produced by the molecule is the average.
