The Organic Chemist's Book of Orbitals

The Organic Chemist's Book of Orbitals focuses on the mechanisms, stereochemistry, and reactivity of molecular orbitals. Composed of four chapters, the book outlines how molecular orbitals are created by delocalization. Concerns include CC and CH single-bond orbitals; bond orbitals and group orbitals; and the localized orbitals of CH2 and CH3 groups. Schematic diagrams are presented to show the nature, reactions, and compositions of molecular orbitals. The text offers a list of molecules and orbital occupancies. Orbital drawings are presented to show the differences of the molecular orbitals of hydrogen, water, ammonia, methane, nitrogen, carbon monoxide, and acetylene. The book also provides an index of references for the molecular geometries and orbital energies employed in the orbital drawings. Considering the weight of data presented, the book is a great find for readers interested in studying molecular orbitals.
