Provides comprehensive coverage of the interpretation of LC-MS-MS mass spectra of 1300 drugs and pesticides. *Provides a general discussion on the fragmentation of even-electron ions (protonated and deprotonated molecules) in both positive-ion and negative-ion modes. *This is the reference book for the interpretation of MS-MS mass spectra of small organic molecules. *Covers related therapeutic classes of compounds such as drugs for cardiovascular diseases, psychotropic compounds, drugs of abuse and designer drugs, antimicrobials, among many others. *Covers general fragmentation rule as well as specific fragmentation pathways for many chemical functional groups. *Gives an introduction to MS technology, mass spectral terminology, information contained in mass spectra, and to the identification strategies used for different types of unknowns.--Provided by publisher.
