摘要：

Ionization of boron trichloride by electron impact has been examined by Fourier transform mass spectrometry. The parent ion, BCl3+, and three fragments ions, BCl2+, BCl+, and Cl+,are observed. The total ionization cross section is 1.0 +/- 0.1 x 10(-15) cm(2) between 30 and 60 eV. BCl+ and Cl(r)eact with neutral BCl3 to yield BCl2+ with bimolecular rates of 5.3 +/- 0.5 x 10(-10) cm(3) s(-1) and 6.2 +/- 0.5 x 10(-10) cm(3) s(-1), respectively. BCl2+ does not react with BCl3. Cl- and Cl-2(-) are produced by dissociative attachment of low-energy electrons to BCl3, and Cl-2(-) is found to rapidly react with BCl3 to form BCl4-.
