Chapter Three discusses the most famous types of commercial Orbitrap analyzers, including LTQ Orbitrap, Orbitrap Elite, Q Exactive Orbitrap,...

There is a popular saying that "water quality is as important as quantity," but most often more importance is accorded in studying hydrodynamics than hydrochemistry. Research and literature on water chemistry are not commensurate with issues or problems with water quality. Though the utility of water depends on its chemical constituents, little efforts are made to analyze, interpret and understand water chemistry. Much human suffering can be reduced if water quality is maintained to required specifications. New techniques can be invented for improving water quality by continuously carrying...

This text was developed from a course for physical chemistry and chemical physics students using cross-polarization (CP) magic angle spinning (MAS) NMR in their laboratory assignments. The book provides students with the details of the CP/MAS experiment as it is used to obtain rare-spin, high-resolution NMR spectra. The design of the CP/MAS experiments and the interpretation of spectra and relaxation measurements require an understanding of the interplay of several fundamental physical interactions not normally encountered in solution NMR. The student can observe the way interacting spin...
