The proton affinities of the acetylene molecule, and of the acetylide and diacetylide ions
Abstract
Non-empirical LCAO–MO–SCF calculations using Gaussian basis sets were used to predict the geometry of the acetylide ion, proton affinities of 547·5, 391·6, and 166·1 kcal/mole being computed for C22–, C2H–, and C2H2, respectively.
