Thermodynamic Functions of Cyanogen and the Equilibrium Constant for the Reaction ½C2N2⇌CN between 1000° and 4500°K

Abstract

T HE parent ions of all even electron molecules have a doublet ground state but in very few cases has it been possible to detect experimentally the two components which arise from the spin-orbital interaction energy of the odd electron.

Statistical thermodynamic functions of cyanogen, dicyanoacetylene, and dicyanodiacetylene

“…DISCUSSION OF THERMODYNAMIC DATA There have been a number of publications on the thermodynamic properties of cyanogen (15,20,24), but in each case no value of the dissociation energy was required, since entropy, heat capacity, the free energy function, ~[(G°-El)/T], and the enthalpy function, (H°-El)/T, were the only thermodynamic functions examined. No thermodynamic data for DCDA were found in the literature.…”
