Raman spectroscopy ( / ˈrɑːmən /) (named after physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. [1] Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which ラマン分光装置は励起光源、レイリー散乱光を除去するフィルター、ラマン散乱光をスペクトルに分解する分光器、検出器で構成されます。光源からの照射光は試料に導かれ、試料を照射し励起します。試料から発生した散乱光はフィルターを通してラマン散乱光だけを分光器に導入し、検出器 Raman spectroscopy sounds very much like infrared (IR) spectroscopy; however, IR examines the wavenumber at which a functional group has a vibrational mode, while Raman observes the shift in vibration from an incident source. The Raman frequency shift is identical to the IR peak frequency for a given molecule or functional group. 通常、ラマンスペクトルは縦軸にラマン散乱強度、横軸にラマンシフト（波数、単位は通常cm-1 ）をとったグラフとなる。 超連続スペクトルの生成. 高強度連続波(CW)レーザーの場合、SRS を用いてスペクトルを広帯域化することができる。 Temperature-dependent Raman studies revealed a red shift in the vibrational modes. Photoluminescent data revealed a blue shift of emission edge, primarily attributed to the annealing-induced alteration in crystallinity, resulting in greater electron-hole emission efficiency.
