Introdu??o às técnicas de reflex?o especular e de reflex?o-absor??o no infravermelho: (2) reflex?o-absor??o

摘要

This paper is the second part of an article aimed to present theoretical basis as well as some applications of two infrared reflection techniques: specular reflection and reflection-absorption. It is emphasyzed how much spectral simulation can aid spectral analysis. The usefulness of reflection-absorption spectroscopy as a thin film caracterization technique is stressed. Optical effects such as LO-TO splittings and their observation as Berreman effect are also addressed.
