Evidence of production of H2CN+-N2. Application to the atmosphere of Titan

Abstract
The molecule H2CN+-N2 has been observed in a mixture of N2-CH4 irradiated by alpha particles from a radioactive source. The equilibrium constant has been measured and the enthalpy of the reaction has been calculated (|ΔH0| = 7.65 ± 0.09 kcal . mole-1)
