Mass Spectrometry of Organic Ions

Mass Spectrometry of Organic Ions PDF Author: F.W. McLafferty
Publisher: Elsevier
ISBN: 032314277X
Category : Science
Languages : en
Pages : 745

Book Description
Mass Spectrometry of Organic Ions covers the underlying theories and major applications of mass spectrometry. This 13-chapter book starts with a survey of the mechanisms by which organic ions can decompose and rearrange, as well as the generalized concept in terms of physical-organic chemistry. The discussion then shifts to the advantages and potential of mass spectrometry in structure determination by the elucidation of the empirical formulas of organic ions. Considerable chapters are devoted to the detailed correlations and mechanisms of the mass spectra of long-chain esters, alkylbenzenes, a variety of natural products, aliphatic compounds, and terpenes. The remaining chapters demonstrate the illustrative power of mass spectrometry in structure of petroleum, which is composed of hydrocarbon mixture. This book will be of great benefit to organic and analytical chemists, scientists, and students.

Hydrogen Bonding

Hydrogen Bonding PDF Author: Steve Scheiner
Publisher: Oxford University Press, USA
ISBN: 019509011X
Category : Science
Languages : en
Pages : 396

Book Description
Because of the importance of the hydrogen bond, there have been scores of insights gained about its fundamental nature by quantum chemical computations over the years. Such methods can probe subtle characteristics of the electronic structure and examine regions of the potential energy surface that are simply not accessible by experimental means. The maturation of the techniques, codes, and computer hardware have permitted calculations of unprecedented reliability and rivaling the accuracy of experimental data. This book strives first toward an appreciation of the power of quantum chemistry to analyze the deepest roots of the hydrogen bond phenomenon. It offers a systematic and understandable account of decades of such calculations, focusing on the most important findings. This book provides readers with the tools to understand the original literature, and to perhaps carry out some calculations of their very own on systems of interest.

Proton Transfer Reaction Mass Spectrometry

Proton Transfer Reaction Mass Spectrometry PDF Author: Andrew M. Ellis
Publisher: John Wiley & Sons
ISBN: 1118683579
Category : Science
Languages : en
Pages : 361

Book Description
Proton Transfer Reaction Mass Spectrometry (PTR-MS) is a rapidly growing analytical technique for detecting and identifying very small quantities of chemical compounds in air. It has seen widespread use in atmospheric monitoring and food science and shows increasing promise in applications such as industrial process monitoring, medical science and in crime and security scenarios. Written by leading researchers, this is the first book devoted to PTR-MS and it provides a comprehensive account of the basic principles, the experimental technique and various applications, thus making this book essential reading for researchers, technicians, postgraduate students and professionals in industry. The book contains nine chapters and is divided into two parts. The first part describes the underlying principles of the PTR-MS technique, including • the relevant ion-molecule chemistry • thermodynamics and reaction kinetics • a discussion of ion sources, drift tubes and mass spectrometers • practical aspects of PTR-MS, including calibration. The second part of the book turns its attention to some of the many applications of PTR-MS, demonstrating the scope and benefits, as well as the limitations, of the technique. The chapters that make up the second part of the book build upon the material presented in the first part and are essentially self-contained reviews focusing on the following topics: • environmental science • food science • medicine • homeland security, and • applications of PTR-MS in liquid analysis.
