 Added by Beat Buesser, value for reaction: CH + N2 = HCNN (B&D #24a) in 'Gas-Phase Combustion Chemistry' (ISBN: 978-1-4612-7088-1), chapter 2, 'Combustion Chemistry of Nitrogen', Anthony M. Dean, Joseph W. Bozzelli",
+Here CH is in its ground state (doublet), as specified in B&D p. 221: The initially formed adduct from CH+N2 is a doublet, and there's a surface crossing to eventually form HCN + N.
