Laser photolysis of Br2-propargyl bromide CH2BrC≡CH mixtures and cavity ring-down detection of the C3H3Br2 radical

The absorption spectrum, absorbance vs. wavelength, at 238-252 nm is shown in Fig. 1

The absolute absorption cross section at 240 nm was measured relative to the absorption cross section of the C3H3 radical
