赤外分光測定法一基礎と最新手法第Ⅱ部　各種測定法第7回11．発光測定法

摘要

1．はじめに発光測定法は，太陽の光，星の光を分光器で分け，温度やその構成物質を判定する手段として古くから用いられてきた．発光スペクトルによる分析を行う場合，試料温度は通常2000c以下のことが多いので，試料から放射される光は非常に弱い．%Infrared emission spectroscopy is useful for measuring infrared spectra from samples which are not tractable by absorption or reflection measurements. Principles of this spectroscopy including KirchhofFs law and Planck's law of radiation are described. Practical methods of measurements to obtain high-quality infrared emission spectra are discussed. For this purpose, reduction of the effects of infrared emission from sources other than the sample under study is essential.
