WebVideo transcript. - [Voiceover] For this NMR, the molecular formula is C9H10O, let's go ahead and calculate the hydrogen deficiency index. So if we have nine carbons, the maximum number of hydrogens we can have, is two times nine plus two. And two times nine, plus two, is equal to 20, so for nine carbons, 20 hydrogens is the maximum number. WebAug 28, 2024 · An NMR can be divided into three main components: the workstation computer where one operates the NMR instrument, the NMR spectrometer console, and the NMR magnet. A standard sample is inserted through the bore tube and pneumatically lowered into the magnet and NMR probe (Figure \(\PageIndex{30}\)).
