The simplest example of a link is an intrawiki link, that is, a link to another page within the ValidNMR wiki, like [[qNMR]]. Only double brackets are needed. This link is called a 'redlink' at present, because the page doesn't exist yet.

Interwiki links (like linking to the Wikipedia entry for NMR, requires a few more keystrokes. Note that we always have double brackets, but this time we 'call out' the Wikipedia entry by starting with 'wikipedia:'. Following that, you type 'nuclear magnetic resonance spectroscopy', which is the name of the Wikipedia page. If you want the embedded link to say 'nuclear magnetic resonance spectroscopy', you end the line with a pipe symbol | right before the closing double brackets. If not, you type the text that you wanted displayed AFTER the pipe symbol.

When placed in a magnetic field, NMR active nuclei (such as <sup>1</sup>H or <sup>13</sup>C) absorb [[electromagnetic radiation]] at a frequency characteristic of the [[isotope]].<ref>{{Cite journal|url=http://www.jaoa.org/content/106/1/23.full|last1=Shah|first1=N|last2=Sattar|first2=A|last3=Benanti|first3=M|last4=Hollander|first4=S|last5=Cheuck|first5=L |title=Magnetic resonance spectroscopy as an imaging tool for cancer: a review of the literature.|journal=The Journal of the American Osteopathic Association |volume=106 |issue=1 |pages=23–27 |date=January 2006 |pmid=16428685}}</ref>  The resonant frequency, energy of the absorption, and the intensity of the signal are proportional to the strength of the magnetic field. For example, in a 21 [[Tesla (unit)|Tesla]] magnetic field, [[proton]]s resonate at 900&nbsp;MHz. It is common to refer to a 21 T magnet as a 900 [[Megahertz|MHz]] magnet, although different nuclei resonate at a different frequency at this field strength in proportion to their [[nuclear magnetic moment]]s.
