A combination of chemical trapping and computations is used to determine the activation parameters far the interconversion of the 3-methylenebicyclo[3.3.1]nonan-7-yl (1), (3-noradamantyl)methyl (2), and 1-adamantyl (3) radicals. The three radicals model proposed intermediate surface radical structures in the chemical vapor deposition (CVD) of diamond on its 2 x 1 reconstructed [100] surface. The study finds that relatively low-level calculations previously applied to the problem of diamond growth are reliable, at least qualitatively.
