Absolute rate coefficients for F + H2 and F + D2 at t = 295 K. Interim report

Technical Report ·
OSTI ID:6917533

The rate coefficients for the F + H2 and F + D2 reactions were determined to be (1.8 plus or minus X 10 to the 13th power and (9.5 plus or minus 1.7) X 10 to the 12th power cm3/mol-sec, respectively. The absolute values and the resultant ratio of H-atom to D-atom abstraction of 1.92 + or minus 0.23 are in agreement with earlier determinations. Fluorine atoms were generated under isothermal conditions in excess argon by means of the infrared multiphoton dissociation of SF6. The reaction between F and H2(D2) was monitored by means of the time-resolved infrared emission from HF subscript(DF subscript). The validity of the experimental method is discussed.
