Reactions of Thermalized Recoil Atoms

The following equation can be derived for the fractional yield Y of CH2=CH18F  

If a third reactant (RH) is present, an additional reaction can take place  

Both equations predict straight lines for graphs of Ych2=ch18f versus [HIMC2H2] with slopes of kjk2 and kblk2, respectively. 

The second group of experiments was performed by Root and coworkers (26-29), using C2F6 as the bath gas and C3F6 as the reference compound. From the reaction 

The formed H18F is quantitatively absorbed on the sample vessel walls, from which it is removed by extraction with a K2C03 solution (28,30).
