An investigation of the negative ion-molecule chemistry of pentachloroethane (PCE) in air based Ion Mobility Spectrometry and Ion Mobility Spectrometry-Mass Spectrometry systems has been undertaken. The observed product ions are Cl-, produced by dissociative electron attachment, and Cl-.HOO resulting from a reaction with O2-. Based upon the moisture content of the system, these ions can be observed as a doublet in a ‘dry’ system or as a singlet in a ‘wet’ system. The nature of the Cl-.HOO product ion was investigated by using isoflurane as a probe to monitor the changing ratios of Cl-and Cl-.HOO as the PCE concentration decreased. This confirmed the origins of the two product anions. Electronic structure calculations have aided to the understanding of the reaction processes observed
