The basic assumptions of the SET model are: (a) there is the possibility of coupling between vibration modes of absorbed water (v) and vibration modes of reaction environment ([omega]), (b) the activated complex for the dehydration is formed via the resonant (selective) transfer of required energy from the reaction environment to resonant vibration mode of absorbed water, (c) the value of transferred energy is quantized and it is determined by the number of resonant vibration quanta (n) which are exchanged between the reaction environment and the resonant vibration mode of absorbed water, (d) resonant transfer of energy causes the change in the value of anharmonicity factor of the resonant vibration mode.
The author has organized his text in five parts, examining ideas and principles, the physics of the electron, the theory of anharmonicity, quantum fields, and radiative corrections, in turn.
It covers the basis required for quantum oscillator studies, single quantum harmonic oscillators, anharmonicity, oscillator populations in thermal equilibrium, quantum normal modes of vibration, damped harmonic oscillators, and vibrational spectroscopy.
The authors discuss how clusters are used as dissipative structures, and how they are subsequently interrelated with fluctuation-free volume models, percolation systems and the Anharmonicity Concept.
