Molecular Solid State Physics (eBook, PDF)

• Format: PDF

Produktbeschreibung

This book elucidates the structure of solids including ionic, molecular and valence crystals and investigates certain of their properties. It looks at surfaces and clusters as potential catalysts. Cooperative effects such as those in alloys and ferroelectrics are described simply. Physical principles are explained in chemical terms. The book addresses primarily post-graduate chemistry students interested in Molecular Engineering.
