赤外分光測定法-基礎と最新手法 第Ⅱ部　各種測定法 第12回　20.二次元相関分光法

摘要

二次元分光法はx軸方向とy軸方向の両方にスペクトrnルを展開し，それぞれのスペクトルに観測されるバンド間rnの相関を見る方法をいう．バンド間の相関を見ることrnによって，一次元のスペクトルではとらえにくいスペクトrnル的特徴をより明確にとらえることができる場合がある．rn二次元分光法のアイデアは元々NMRの分野で生まれrnた．%This article outlines two-dimensional correlation spectroscopy proposed and developed by Noda. Two-dimensional correlation spectroscopy is a powerful spectral analysis method and has been used extensively in infrared spectroscopy and other related spectroscopy such as near-infrared spectroscopy and Raman spectroscopy. In this article we describe basic principle, characteristics and applications of two-dimensional correlation spectroscopy. We also mention how one can read out two-dimensional correlation spectra.
