Abstract
The approximate study of the restricted rotation of molecules near a surface is extended to an unsymmetrical diatomic molecule, hydrogen iodide, and a ring molecule, benzene, for a graphite surface in each case. Calculations of the factor R in the BET constant C=R exp(ε1—Λ)/kT are carried out for these cases. R is found to be of the same order of magnitude (2–20) as for the symmetrical diatomic molecule.Keywords
