The Nature of the Electronic Excited States of Molecular Systemsn uses the gyroscopic model in order to illustrate the rotating wave approximation. The model is made more relevant by adding damping and losses to it. The experimental conditions leading to the formation of photon echoes are reviewed and interpreted in terms of the gyroscopic model..The fifth secti

We discuss the almost universal role of fluctuations of host-lattice nuclear spins in determining the homogeneous linewidths of metastable optical levels at low temperatures (T < 4K), and point out that the dynamics of these nuclear spins are strongly modified by the presence of the
