This book covers a range of new research on computational quantum chemistry, along with a special section devoted to exotic carbon allotropes and spiro quantum theory. The section on spiro quantum theory covers the technical presentation of the ideas surrounding the emergence of a synthetic, analytical, and theoretical spiro quantum chemistry edifice, as well as a chemical topology scheme that successfully describes molecules and patterns, including the hydrocarbons and allotropes of carbon. The second part of the book covers a range of new research on computational quantum chemistry.

Spiro Quantum Chemistry is a popular as well as technical presentation of the ideas surrounding the emergence of a synthetic, analytical, and theoretical spiro quantum chemistry edifice, as well as a chemical topology scheme that successfully describes molecules and patterns, including the hydrocarbons and allotropes of carbon. In particular, the purpose of this book is to describe the generalization and realization of the organic chemistry concept of spiroconjugation into 1-, 2- and 3-dimensions. The book is divided into three parts: The first part describes spiroconjugation and presents a C lattice that exhibits the spiroconjugation phenomena in fully 3-dimensions. It also described the corresponding 1-dimensional substructures of this lattice that exhibit spiroconjugation delocalized in 1-D. The second part presents experimental evidence for the synthetic realization of this so-called glitter allotrope of C that is spiroconjugated in 3-D, and present evidence why this synthetically realized C allotrope has a metallic status. The third part describes the chemical topology of the glitter C allotrope and of the other commonly known allotropes of C.This chemical topology enables one to map the C allotropes, including glitter, in a topology space allowing one to classify them. This unique book provides insights into the potential richness of organic chemistry in terms of a source of a metallic allotrope of C. The reader will learn to appreciate the generalization of the spiroconjugation phenomenon in 1-D, 2-D, and 3D as a concept in organic chemistry.
