查询词典 absorption bands

The results show that the mean particle size of α-Fe2O3 monolayer is about 58 nm. There are characteristic bands at 568, 482 and 386 cm~(-1) in IR spectrum. The absorption of 375 nm in UV-Vis spectrum is the electron transition of ferric and oxygen atom.

结果表明，α-Fe2O3单层膜是由粒径约为58 nm的粒子排布而成，在568、482和386 cm-1处有特征红外吸收峰，在紫外区375 nm处存在明显的吸收，为Fe-O间的电子跃迁，其吸光度值与膜层数间的较好线性关系说明在一定的速度下挂膜，可以将氧化铁溶胶中的纳米粒子较好地转移到基片上。

The UV-visible spectra show two bands corresponding to the transverse and longitudinal surface plasmon absorption at 532 and 720 nm, respectively, for the colloidal GNFs.

可见紫外线光谱分析显示，胶状纳米金花的横向和纵向表面等离子体的吸收波段分别是532和720纳米。

The absorption band at 2240 A discovered by Stucklen in an underwater spark does not agree with the band observed by Hulthen and Zumstein in a high temperature oven and later studied by Grundstrom. The important difference lies in the complete lacking of the R-branch lines in Stucklen's band. New experimental investigation led to the discovery of the unfound R-branch lines. This is a strong evidence that the bands are actually the same.

Stcklen氏发现用铜极在水中生火花有一吸收光带位於2240A区域此光带与Hulthen氏及Zumstein氏及Grund-strom氏在高温度炉中用铜之蒸气加以氢气所得之吸收光带(亦在2240A附近)不能一致最大之分别在Stucklen之光带全无R支谱线新实验工作发现R支谱线之存在得R(0)至R(13)之十四根线确实证明Stucklen之光带并非另一新带。

Perylene tetracarboxylic diimide derivatives are important molecular building blocks that are currently being investigated for use in a variety of photoactive organic materials because of their low light and thermal fading rates,high luminescence efficiency,wide absorption and emission bands in visible region,and optoelectronic properties.

苝二酰亚胺(Perylene tetracarboxylic acid diimide，简称PDI)类衍生物具有优异的热和光化学稳定性，对可见区到红外区的光有很强的吸收。是一种具有独特的光物理和光化学性质的有机光电材料。

For example, it can be easily stated that this result will play a key role for distinction of saline soil and sandy soil on the satellite images due to the absorption in long spectral bands for lower soil layers of CSS.

例如，它可以很容易地指出，这一结果将起到关键作用的区别盐渍土和沙质土壤上的卫星图像，由于在长期的吸收谱带较低土层的CSS 。

Using these constants and QFT〓 method, we calculated the N〓-broaden widths of the observed absorption lines for (202) band. Also we obtained the N〓-broaden widths and temperature dependences of lines in the 〓R (1, 1) branch of (202),(122), and (004) bands.

利用这些常数值和QFT方法，分别计算了水汽分子（202）带中已有实验数据的一些谱线的氮分子碰撞加宽线宽，以及（202）、（122）、（004）带〓R（1，1）支谱线的氮分子碰撞加宽线宽，和线宽的温度依赖关系。
