The Structure of Coronene

The identification of Coronene  (m/z 300) by (GCMS) Gas Chromatography mass spectrometry.

The identification of coronene based on a specific m/z value requires careful consideration and should be supported by additional evidence. While m/z 300 can be a characteristic fragment ion associated with coronene, it is important to note that mass spectra can vary depending on instrument settings, ionization techniques, and other factors.
