Two absorption features at 164.71 and 168.33 nm have been detected from the vacuum ultraviolet flash photolysis of either Sn(C/sub 2/H/sub 3/)/sub 4/ or Hg(C/sub 2/H/sub 3/)/sub 2/. The features are assigned to the vinyl radical on the basis of precursor, kinetic data, and the spacing between the bands. Extinction coefficients of 1650 /plus minus/ 500 and 1120 /plus minus/ 500 cm/sup /minus/1/ atm/sup /minus/1/ (Napierian) for the two bands, respectively, have been measured, and a rate constant of (6.7 /plus minus/ 2.7) /times/ 10/sup /minus/12/ cm/sup 3/ molecule /sup /minus/1/ s/sup /minus/1/ for the reaction of C/sub 2/H/sub 3/ + O/sub 2/ has been determined.
