Chemical ionization of a mixture of nitrogen and carbon monoxide produces three stable isobaric species at m/z 56: OCCO, OCNN and NNNN radical cations. Separated at increased resolution, these ions are readily identified by collisional activation. Neutralization–reionization experiments performed on two different mass spectrometers have not allowed the detection of any recovery signals for the corresponding neutrals.
