Semiclassical mechanics relates Newton's classical theory to modern quantum mechanics in a manner that is designed for the interpretation of recent experiments. The theory is physically intuitive and computationally accurate and is seen as particularly powerful for large quantum numbers - hence it has special reference to atomic, nuclear and molecular physics - but it also is regarded accurate even for the lowest quantum states. This book aims to provide a comprehensive account of the application of the theory to molecular systems, with particular attention paid to the problems of non-separability. Although it is primarily a research monograph, the inclusion of problems at the end of each chapter intends to make it equally applicable as a graduate text.
