ultraviolet-absorption spectra 解釋
紫外光吸收光譜
  • ultraviolet : adj. 【物理學】紫外的；紫外線的；產生[應用]紫外線的。n. 紫外線輻射。
  • absorption : n. 1. 吸收，合併。2. 專心，一心不亂，熱中 （in）。3. 〈口語〉飲食。
  • spectra : n. spectrum 的復數。
  1. All data indicated that f i was a pure substance. third, using modern analytic techniques such as nucleic magnetic resonance ( nmr ), infrared spectroscopy ( ir ), ultraviolet visible absorption spectra ( uv ) and mass spectrometry ( ms ), we analyzed the basic chemical structure of f i and nominated it phthalic acid di ( 3 - methyl ) nanyl ester ( pdne ). we estimated primarily it was a novel natural compound

    第三，利用核磁共振，紅外光譜，紫外分析，質譜等現代分析測試技術對分離提取物f進行結構鑒定，解析出f的結構，初步推斷該物質為鄰苯二甲酸- （ 3 -甲基）壬酯（ pdne ） ，根據目前所掌握的資料，還沒有檢索到該物質相關的報道，初步認定為一種新型的天然產物。
  2. Ultraviolet absorption detector, photodiode array detector ( dad ), fluorescence detector, and electrochemical detector are optional detectors, response value of which is relative to not only quality of the object under test, but also structure of the compound ; refractive index detector and evaporative light - scattering detector are universal detector, responding to structure of all compounds ; evaporative light - scattering detector is quality - type detector, whose responding value only relates to quality of the object under test for compounds with similiar structures ; photodiode array detector ( dad ) can, at the same time, record absorption spectra of the object under test in a prescribed wave scope, consequently, it can be used in spectrum control and inspection of purity of chromatographic peaks of the object under test

    紫外、二極體陣列、熒光、電化學檢測器為選擇性檢測器，其響應值不僅與待測物的質量有關，還與化合物的結構有關；示差折光檢測器和蒸發光散射檢測器為通用型檢測器，對所有的化合物結構均有響應；蒸發光散射檢測器屬質量型檢測器，對結構類似的化合物，其響應值幾乎僅與待測物的質量有關；二極體陣列檢測器可以同時記錄待測物在規定波長范圍內的吸收光譜，故可用於待測物的光譜管制和色譜峰純度的檢查。
  3. The infrared results showed that the ir characteristic value l080cm - lof cubic crystal sio, and the absorption peak 460cm - l of mgf, caused by the interaction between f - - mg ' + - p elastic vibration and photon radiation, appeared in the ir spectra. ellipsometric analysis showed that the typical absorption peaks 58lnm, 589nm and 606nm, resulting from the surface plasma resonance of cu panicles and reflecting the absorption on composite film system, appeared in the extinction coefficient k curves of cu ( voll5 % ) mgf, cu ( vol20 % ) mgf, and cu ( vol30 % ) mgf, cermet films, respectively. with the component of cu increasing, the peak site presented red shift, which was in accordance to the results of ultraviolet - visible spectra

    橢偏測試分析表明： cu （ vol15 ） mgf _ 2 、 cu （ vol20 ） mgf _ 2和cu （ vol30 ） mgf _ 2樣品的消光系數k曲線中出現了反映復合金屬陶瓷體系吸收的由cu金屬顆粒表面等離子體共振引起的吸收峰，峰位分別為581nm 、 589nm和606nm ，呈現紅移，這些與紫外-可見光譜測試結果相一致；此外， cu - mgf _ 2復合納米金屬陶瓷薄膜光學常數的實驗值與考慮尺寸效應修正過的mg理論值總體上符合得很好。
