A unique formation and excitation of the CN molecule occurred in the resonance tube. (Observed in connection with the investigation of the mercury hydride molecule.) The bands which were noted belong to the 2Σ → 2Σ electronic system. The excitation has been determined to be due to collisions of the CN molecule with excited mercury atoms in the 63P state.
