. Energies (ΔE, eV) and Gibbs energies (ΔG, kJ/mol) of dimerization reactions 2M + 2CH2 → D + 4NX2 (X=O or F; M = monomer CL-20, CSi5H6N12O12 or C4Si2H6N12F12; D is the corresponding low-energy dimer, presented in Fig. 3). Binding energies (BE, eV) for the N–CH2 bonds in the dimers are also presented. .
