Matrices,arbitrary although there are some distinct advantages in the choice of a set of mutually orthogonal coordinates. In some situations, the orientation of the vector in space must be changed. The simplest change involves a rotation of the vector to a new orientation so that its direction, but not its l

Vibrations and Normal Modes,spatial directions, rotate about two orthogonal axes associated with significant moments of inertia, and vibrate along the internuclear axis. In general, however, a molecule moving in space will display all such motions. The observer really observes the motion of the two atoms of the molecule. These

Kinetics,Each row of the matrix system was generated by the equation of motion for a single particle. Diagonalizing this total system of equations gave a new coordinate system in which there was no coupling between the different coordinate directions and the system resolved into a set of . independent scalar

Other Techniques: Perturbation Theory and Direct Products,eneral, matrix descriptions of physical systems will not be so tractable. However, the complicated matrices can often be analyzed when their elements differ slightly from those of a second matrix whose eigenvalues and eigenvectors are known. This is the purpose of perturbation theory.
