I am working on analyzing the mass spectrum of pentabromophenol but am struggling to determine the fragment at 60 m/z. It could possibly be 5 carbons however that is too much positive charge to exist at high abundance.

Below are the mass spec retrieved experimentally and from literature.

Literature Mass spec: NIST WebBook

Experimentally determined mass spectrum: Literature mass spec.

It seems to have the 1:1 $\ce{Br}$ ratio spaced by 1.

I think a reasonable assignment would be that it is $\ce{[BrCCOH]^2+}$

m = 120 and 122

m/z = 60 and 61
