Opis

The theory of molecular quantum electrodynamics and its application to a number of intermolecular interactions Considerable advances have taken place in quantum electrodynamical theory of intermolecular forces. Virtually impacting all areas of science, molecular quantum electrodynamics (MQED) has been successfully applied to numerous radiation-molecule and molecule-molecule processes. Molecular Quantum Electrodynamics delves in depth into the MQED theory of long-range intermolecular forces, offering a variety of physical viewpoints and calculational techniques. The text provides an introduction and background on:

• Field theoretic treatments, including the second quantized Maxwell field formulation
• Intermolecular potential and a semi-classical perturbation theory treatment of short- and long-range forces
• Retarded dispersion interactions including discriminatory forces
• Intermolecular interactions in a radiation field
• Energy shift and transfer rate in relation to specific two- and many-body forces

Molecular Quantum Electrodynamics provides an essential resource for chemists, physicists, biophysicists, materials scientists, and nanochemists interested in exploring the theory and application of MQED.
