Molecular motion, in general, is described by classical mechanics at normal conditions and through quantum mechanics at low temperatures. Both theories are presented in this chapter, with classical mechanics based on the hamiltonian function that depends on the position and momentum degrees of freedom of the system. The calculation of the trajectories of the particles is presented as well as the determination of the states of the system in the (phase) space of positions and momenta. Quantum mechanics is presented through its principles and the hamiltonian is used for the production of the energy levels of a number of model systems. These systems are used for the description of the molecular rotation and vibration.
