The shape of the absorption line in magnetodilute samples at low temperatures is analyzed by the memory function method.

Line shapes describe how absorption and emission are spectrally distributed around the line positions formed by rotational, vibrational, and electronic transitions. Line shapes arise from the different processes that spectrally broaden the absorption and emission of radiation.

The fundamental line shape functions for atmospheres including the Gaussian line shape due to molecular motion and the Lorentzian line shape from lifetime broadening, including collision (pressure) broadening are described.

Abstract The restoring forces on membranes are due to the applied tension, while the restoring forces for plates are due to the flexural rigidity of the plate’s material.

Instead of applying boundary conditions at one or two points, those constraints will have to be applied along a line or a curve. In this way, incorporation of the boundary condition is linked inexorably to the choice of coordinate systems used to describe the resultant normal mode shape function

It is shown that the relationship between parameters obtained by the Warren-Averbach approximation and integral-breadth methods becomes possible.

In their model, phonons with finite wave vectors contribute to the line through an uncertainty principle argument. For the phonon envelope function, Richter selected a Gaussian whose magnitude is one-half at the grain boundary. We have now calculated the Stokes line for various microcrystalline semi-conductor
