chloroform or carbon disulfide. Mass spectral data were recorded with electron
impact ionization at 70 eV.
While retaining the basic structure of the previous editions, numerous reference
entries have been updated and new entries have been added. Altogether, more than
10% of the data is new. The chapter on 15 N and 29 Si NMR is entirely new and
the section on mass spectrometry now contains fragmentation rules for MS/MS
analysis after soft ionization.
