Introdu??o às técnicas de reflex?o especular e reflex?o-absor??o no infravermelho: (1) reflex?o especular

摘要

This paper is the first 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 the Kramers-Kr?nig analysis of reflection data can be useful in both retrieving optical constants and making spectral analysis possible. Examples of vitreous, powdered and liquid samples are given.
