This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed during the last two centuries by many experimental discoveries and from the theoretical side by the introduction of quantum physics to the adequate description of micro-particles.

The book is the first to provide a broad overview on how to solve the forward problem to calculate accurate seismograms in 3D Earth models, to compare theory with observations and to iteratively update Earth models until a satisfactory fit to observations is achieved.
