"This book provides a theoretical basis for the molecular phenomena observed in confined spaces. State-of the-art theoretical and computational approaches are described, with a focus on obtaining physically relevant understanding, enabling the reader to build a good appreciation of the underlying chemical principles. a̲²́ƠË₋Real life' examples of confined systems are presented, highlighting how the reactivity of atoms and molecules changes upon encapsulation. Recent developments related to the following host-guest systems are discussed. *A̲ Cucurbit[n]uril *A̲ ExBox 4 *A̲ Clathrate hydrates *A̲ Octa acid cavitand *A̲ Metal organic frameworks (MOFs) *A̲ Covalent organic frameworks (COFs) *A̲ Zeolites *A̲ Fullerenes *A̲ Carbon nanotubes."-- Provided by publisher.
