General note | dc.description | Artículo de publicación ISI | es_CL |
Abstract | dc.description.abstract | When the target is in the solid state, most infrared spectral features are manifestly asymmetric; hence, a line
shape function well-grounded in theory is necessary to ascertain the net energy taken by the associated electronic
transition. The main sources for spectral line broadening, asymmetry, and shift, no matter the transferred
energy, are multiphonon events involving the acoustic vibrational modes. A simple closed-form mathematical
expression for the phonon-broadened lineshapes, shown to be valid at low temperatures, and linewidths on
the order of the Debye energy of the solid or smaller, giving remarkable agreement with experiment is studied
in connection with its utility for analyzing infrared spectral features. | es_CL |
