Molecular spectroscopy

Molecular spectroscopy

*Ideal for upper-level undergraduate/beginning graduate courses in Molecular Spectroscopy; assumes prior knowledge of quantum mechanics. *Blending tradition with innovation, this lively and engaging text presents the basic theories underlying spectroscopy while incorporating modern viewpoints of practical utility in spectroscopy research. Written in a clear, jargon-free style that encourages independent thinking and active participation, it covers the quantum mechanical theoretical basis of spectroscopy, modern innovations in spectroscopy (such as time-dependent theory) and practical applications of spectroscopy research, including the influence of condensed phases.

Molecular spectroscopy

This book 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, the second chapter lays out the essential quantum mechanical tools required to understand spectroscopy. Very little previous knowledge is assumed; mathematics is kept to a minimum, the treatment being only semi-quantitative. The following chapter uses this quantum mechanical framework to establish the selection rules which govern spectroscopic transitions. Chapters 4 - 7 describe the various branches of spectroscopy covered by the book; rotational, rotational - vibrational, Raman, and electronic spectroscopy. Quantum mechanics is used to derive formulae for the various energy levels involved and for the relative intensities of different types of transition. From these, the appearances of the different types of spectra are derived. The molecular parameters on which these spectra depend are defined and the structural information which can be derived from these is discussed.
