(see Table ) show a slight elongation, measuring approximately 1.58 Å and 1.56 Å, respectively. This elongation is noteworthy, as it suggests that the carbons in the JP-10 (exo-TCD) experience some degree of strain, which extends the bond lengths slightly beyond the standard ethane bond length of 1.54 Å. This observation is useful in understanding how strain influences the molecular geometry of hydrocarbons like exo-TCD, potentially contributing to the storage of energy in the molecule.
