Collisional activation spectra. Gas phase [C12H10O]+˙ and [C12H9O]+ ions from dephenyl ether,diphenyl carbonate,and o-, m- and p-phenylphenol

C₁₂H₁₀O]⁺˙ ions in the mass spectra of diphenyl ether and diphenyl carbonate have the same structure, but one which differs from that of these ions from phenylphenol. C₁₂H₉O]⁺ ions from all three compounds have isomerized to a common structure.
