Broadband rotational spectroscopy provides a new method by which plasma chemistry can be explored.Molecules and complexes form when precursors within an expanding gas sample are allowed to interactwith plasma generated by an electrical discharge or laser vaporisation of a solid. It is thus possible toselectively generate specific molecules or complexes for study through a careful choice of appropriateprecursors. It is also possible to survey an extensive range of the products formed under a given set ofinitial conditions in an approach termed ‘‘broadband reaction screening’’. Broadband rotationalspectroscopy provides an opportunity to simultaneously monitor the transitions of many differentchemical products and this allows broader details of reaction pathways to be inferred. This Perspectivewill describe various experimental approaches and review recent works that have applied broadbandrotational spectroscopy to study molecules and complexes generated (in whole or in part) throughchemistry occurring within transient plasma.
