Early studies of JP-10 have primarily focused on its thermodynamic and combustion characteristics , providing valuable insights into its reaction pathways . For instance, reported the gas-phase enthalpy of formation for TCD, with subsequent studies expanding on the liquid-phase thermochemistry and thermochemical properties of exo-TCD-derived radicals . Computational studies, such as those by Zehe and Jaffe, have employed high-level ab initio methods to determine the enthalpies of formation for both exo-and endo-TCD isomers . However, despite progress in thermodynamic modelling, there remains a gap in detailed spectroscopic studies, particularly regarding the structural and electronic properties of JP-10's conformers .
