Molecular Symmetry

• Broschiertes Buch

Produktbeschreibung

Symmetry in Chemistry carefully introduces the subject by combining symmetry with spectroscopy in a clear and accessible manner. Beginning with an introduction to symmetry in nature and chemistry, the text goes on to examine point groups, the interaction of light with molecules, electronic spectra of transition metal complexes with a final chapter on symmetry and the spectra of complexes. Each chapter introduces the subject gradually and ends with a series of self-test questions to enhance student understanding.

Das gut verständliche Lehrbuch führt ein in die Grundlagen des Themas, also in die Symmetriepunktgruppen sowie in die Grundzüge der Wechselwirkung zwischen Licht und Molekül. Behandelt werden überdies Elektronenspektren von Übergangsmetall- und anderen Komplexen.

Rezensionen

"The work will prove to be a popular choice as a textbook or as anadditional resource for group theory and advanced inorganicchemistry courses." ( CHOICE , November 2009)

"A major strength of this book is its accessibility to thepractically and conceptually minded chemist; the reader is led intothe subject through strong visual presentation of the ideas andalthough the mathematics is by no means ignored, it is presentedwithin an applied context." ( The Higher Education AcademyPhysical Sciences Centre Reviews , May 2009)
