This figure shows a mass spectrum of <a href="https://en.wikipedia.org/wiki/Titan_(moon)" class="extiw" title="en:Titan (moon)">Titan</a>'s <a href="https://en.wikipedia.org/wiki/ionosphere" class="extiw" title="en:ionosphere">ionosphere</a> near 1200 kilometers (750 miles) above its surface. The mass range covered goes from <a href="https://en.wikipedia.org/wiki/hydrogen" class="extiw" title="en:hydrogen">hydrogen</a> at 1 <a href="https://en.wikipedia.org/wiki/dalton_(unit)" class="extiw" title="en:dalton (unit)">dalton</a> to 99 daltons per elementary charge. This mass range includes compounds with 1, 2, 3, 4, 5, 6, and 7 <a href="https://en.wikipedia.org/wiki/carbon" class="extiw" title="en:carbon">carbons</a> as the base structure (as indicated in the figure label). The identified compounds include multiple carbon <a href="https://en.wikipedia.org/wiki/molecule" class="extiw" title="en:molecule">molecules</a> and carbon-<a href="https://en.wikipedia.org/wiki/nitrogen" class="extiw" title="en:nitrogen">nitrogen</a>-bearing species as well.
