Comments: The absorption cross sections of CF3H, CF3Cl, and CF3Br and the fluorescence cross sections for their photofragments 
are measured in the 106-155 nm region using synchrotron radiation as a light source. 
The threshold wavelengths for producing the CF3 UV fluorescence from photodissociation of CF3X (X=H, Cl, and Br) are 113.0, 122.2, 
and 132.4 nm, respectively.
