The mass spectrum of nitrogen dioxide is illustrated here. 

(a) Identify the cations present for each of the four peaks in the mass spectrum.

(b) Does the mass spectrum provide evidence that the two oxygen atoms are attached to a central nitrogen atom (ONO), or that an oxygen atom is at the center (NOO)? Explain.
