Reactive Removal of BiF Ground State

Abstract

The reactivity of the ground state of bismuth monofluoride has been investigated with a number of fluorine atom donors at several different temperatures. The measurements have been accomplished both by means of a time resolved, photolytically initiated experiment and on steady-state densities in a flow tube reactor. Both methods provide consistent results. The rate coefficients obtained span a range of over 3 orders of magnitude: F2 is found to be fairly efficient while the series of nitrogen fluorides NF2, NF3, N2F4 is quite inert. We observe BiF(XO+) formation with a rate coefficient of 8.1 x 10- 12 cm3/molecule-sec from NF2 + Bi following the photolysis of Bi(CH3)3 at 193 nm. We are also able to estimate a formation constant for Bi + F2. The stability of Bi(CH3)3 with NF2 is discussed. (JS)
