Any Chemistry Mass Spectrum nerds help !!!!!!

I need help I am looking at the mass spectrum for luminol and I am tying to name and Draw the structure of the fragments which corresponds to the peak at 119 m/z, 92 m/z and 91 m/z
I have put the mass spectrum below if anyone can help me it would be gladly appreciated thanks :smile:
