Molecular spectroscopy provides a straightforward introduction to the spectroscopy of diatomic molecules and is written at the level of intermediate undergraduate courses in physical chemistry and chemical physics. Following a general introduction to the subject, Chapter 2 lays out the essential quantum mechanical tools required to understand spectroscopy. Chapter 3 uses this quantum mechanical framework to establish the selection rules which govern spectroscopic transitions. Chapters 4-8 describe the various branches of spectroscopy covered by the book: rotational, rotational-vibrational, Raman, electronic, and photoelectron spectroscopy. Very little previous knowledge is assumed and mathematics is kept to a minimum. The author uses a range of examples to describe how spectra arise and what information on the structure of the molecules can be acquired from their study.

This primer provides an introduction to the subject of surfaces at the level of undergraduates and first year postgraduates. There are four chapters, the first concerns basic thermodynamic material used to understand the properties of surfaces including; surface tension, Gibbs adsorption, surface pressure and surface phase equilibria, surfactants and micelles, wetting, detergency, and contact angle. The second chapter concentrates on gas adsorbtion at solid surfaces and covers topics including adsorbtion, Langmuir isotherms, heats of adsorbtion, BET isotherms, physisorbtion, chemisorbtion, precursor adsorbtion kinetics, well-defined surfaces, UHV, surface sensitivity and selectivity, surface diffusion and electrons interacting with matter. Chapter three then outlines the physico- chemical principles of XPS, AES, LEED, STM, AFM, work function measurements, UPS, TPD, molecular beams, HREELS and PAIRS and the types of fundamental surface information each of these techniques provides. The final chapter contains a series of worked examples and problems, bringing together the various strands developed in Chapters 1-3 in order to elucidate surface phenomena. The book is unique in its mix of 'Classical' and 'Modern' surface science and should be relevant to physicists, chemists and material scientists.

Neutral reactive intermediates -- radicals, carbenes, nitrenes, and aryenes -- occupy a fascinating place in the history of organic chemistry. First regarded as mere curiosities, neutral reactive intermediates ultimately came under the intense scrutiny of physical organic chemists from a mechanistic point-of-view. This concise text concentrates on how these electron-deficient species now play a key role in synthetic chemistry research. Important reactions are clearly and simply laid out with carefully chosen examples that illustrate their use in organic synthesis. Each chapter includes problems as well as suggestions for further reading. Undergraduates will find Reactive Intermediates an invaluable summary of this important topic in organic chemistry--one that fills a gap created by the superficial treatment accorded these valuable compounds in most chemistry textbooks.

Shattered Symmetry

Group Theory From the Eightfold Way to the Periodic Table

Author: Pieter Thyssen,Arnout Ceulemans

Publisher: Oxford University Press

ISBN: 019062017X

Category: Science

Page: 400

View: 1557

The standard model of subatomic particles and the periodic table of the atoms have the common goal to bring order in the bewildering chaos of the constituents of matter. Their success relies on the presence of fundamental symmetries in their core. The purpose of the book is to share the admiration for the power and the beauty of these symmetries. The reader is taken on a journey from the basic geometric symmetry group of a circle to the sublime dynamic symmetries that govern the motions of the particles. The trail follows the lines of parentage linking groups upstream to the unitary symmetry of the eightfold way of quarks, and to the four-dimensional symmetry of the hydrogen atom. Along the way the theory of symmetry groups is gradually introduced with special emphasis on graphical representations. The final challenge is to open up the structure of Mendeleev's table which goes beyond the symmetry of the hydrogen atom. Breaking this symmetry to accommodate the multi-electron atoms requires to leave the common ground of linear algebras and explore the potential of non-linearity.
