Book Description
Time is an important factor in physical and natural sciences. It characterizes the progress of chemical and biochemical processes. Mass spectrometry provides the means to study molecular structures by detecting gas-phase ions with the unique mass-to-charge ratios. Time-resolved mass spectrometry (TRMS) allows one to differentiate between chemical states that can be observed sequentially at different time points. Real-time mass spectrometric monitoring enables recording data continuously with a specified temporal resolution. The TRMS approaches – introduced during the past few decades – have shown temporal resolutions ranging from hours down to microseconds and beyond. This text covers the key aspects of TRMS. It introduces ion sources, mass analyzers, and interfaces utilized in time-resolved measurements; discusses the influence of data acquisition and treatment; finally, it reviews most prominent applications of TRMS – in the studies of reaction kinetics and mechanism, physicochemical phenomena, protein structure dynamics, biocatalysis, and metabolic profiling. It will assist science and engineering students to gain a basic understanding of the TRMS concept, and to recognize its usefulness. In addition, it may benefit scientists who conduct molecular studies in the areas of chemistry, physics and biology.

Book Description
Methods of Experimental Physics, Volume 3, Part B: Molecular Physics, Second Edition presents the basic principles of electron spin resonance spectrometers and the electron spin resonance spectroscopy. This four-chapter text addresses the concept of thermal equilibrium and relaxation. Some of the topics covered in the book are the features of nuclear quadrupole resonance spectrometers; basic principles of radio-frequency spectrometers; computer methods in magnetic resonance; components of electron spin resonance spectrometer systems; and the resonance condition. Other chapters deal with the ionization potential of free radicals, the electron affinities by mass spectrometric methods, and the experimental methods for determining appearance potentials. The discussion then shifts to the theory of the incoherent neutron scattering and its application to molecular dynamics. The final chapter is devoted to the spectrometer operation and design. The book can provide useful information to chemists, physicists, students, and researchers.
