奇怪的二氧化钛uv-vis吸收谱图已有1人参与 蓝色的是买的二氧化钛测得吸收谱,墨绿色的是烧蚀过后测得吸收谱,是不是我买的样品有问题?为什么紫外区域没有吸收增强?烧蚀过后怎么变成了一个吸收峰? Graph1.jpg回复此楼» 猜你喜欢诚招催化方向有编制副教授 已经有2人回复 氢燃料电池材料全氟磺酸树脂 已经有53人...
奇葩的UV-vis 曲线图黑色曲线为纯的二氧化钛,红色曲线为掺杂的二氧化钛,沿着曲线做切线可以得到样品吸收边际,但掺杂后的样品在可见光处吸收能力较强,出现了个包状,请问高手如何来确定吸收边际,可否画两条切线?是否有相关的参考文献?能否从UV-vis图中得出杂质能级,急求!谢谢! Graph1.jpg回复...
Multiwfn能够直接从ORCA的输出文件中读取数据绘制IR、Raman、VCD、UV-Vis和ECD光谱。需要用到关键词参看Multiwfn手册3.13.2节的详细说明。对于UV-Vis和ECD,不仅支持ORCA的TDDFT、TDHF、CIS、ZINDO、EOM-CCSD、(DLPNO-)STEOM-CCSD的输出,还支持内嵌在ORCA里的能够快速计算很大体系的sTDA和sTD-DFT任务的输出。从ORCA...
Following the Beer-Lambert Law, the plot of absorbance versus concentration should be linear if the absorbance of a series of sample solutions with known concentrations is measured and plotted against equivalent concentrations. This graph is known as a calibration graph. Instrumentation of UV-Vis Spec...
Based on these data, Multiwfn is able to plot theoretical UV-Vis spectrum. Now we do this. Boot up Multiwfn and input TDDFT.out 11 //Plot spectrum 3 //UV-Vis 0 //Show the spectrum on the screen Now you can see below UV-Vis graph ...
The most innovative microvolume UV-Vis Spectrophotometers made in Germany for fast and accurate nucleic acids and protein quantification. No maintenance ever.
Their UV/vis spectrum depends on the nature and relative positions of auxochromic substituents on the basic skeleton. To predict the maximum absorption bands for the current series of anthraquinones, excited sate calculations were performed using TD-DFT, CIS, ZINDO methods. The results showed that ...

ZnS的固体粉末测的UV-VIS吸收光特性曲线 在350nm 左右附近 3个不同的样品 都出现了一个波峰 请教一下是由于什么原因出现的这个波峰,我一直在想是不是由于UV 和VIS 之间转换的时候LAMP交换之后出现的这个波峰,还是我自己本身做的材料有缺陷? 请懂得朋友 帮忙解答一下 谢谢 Graph1.jpg [ Last edited by xhbghz...
