Abstract
Abstract Ionization of boron trichloride by electron impact has been examined by Fourier transform mass spectrometry. The parent ion, BCl 3 + , and three fragment ions, BCl + , and Cl + , are observed. The total ionization cross section is 1.0 ± 0.1 × 10 −15 cm 2 between 30 and 60 eV. BCl + and Cl + react with neutral BCl 3 to yield BCl 2 + with bimolecular rates of 5.3 ± 0.5 × 10 −10 cm 3 s −1 and 6.2 ± 0.5 × 10 −10 cm 3 s −1 , respectively. BCl 2 + does not react with BCl 3 . Cl − and Cl 2 − are produced by dissociative attachment of low-energy electrons to BCl 3 , and Cl 2 − is found to rapidly react with BCl 3 to form BCl 4 − .
