8.13 Mass Spectra of Common Solvents and Matrix Compounds
8.13.1 Electron Impact Ionization Mass Spectra of Common Solvents
The label {50} indicates that the intensity scale ends at 50% relative intensity and
is subdivided in 10% steps. In these cases, the height of the base peak has to be
doubled to bring it to 100%. All spectra represent positive ions only.
