理论上讲，如果两者结合，会产生一个新的物质，此物质就会有自己的紫外吸收峰。但是现在我测不出来，不...
仪器好像能自动标峰
只要有电子跃迁，就会有紫外可见吸收，除过带隙特别大的，几乎所有的材料（有机与无机材料）都有紫外...
The measurements of ultraviolet-visible (UV-VIS) spectroscopy, photopolymerization with differential scanning calorimeter (photo-DSC) and degree of conversion (DC) determination were performed. Results showed that the UV-VIS spectra of all APO and BAPO derivatives possessed lambda max ranging between ...
同意，drs一般是要用积分球附件做的，用于测固体粉末，需要压片
The UV-Vis transmittance spectra of the (composite) NFC films were recorded with a UV– Vis spectrophotometer (Cary 300 Conc, Varian) by scanning within the wavelengths of 200- 700 nm at a scan speed of 120 nm/min and slit of 1.0 nm for analysis. ...
The online UV/Vis + Spectra Data Base is a not-for-profit project established in August 2000 and operated in accordance with the "Open Access" definitions and regulations of the CSPR Assessment Panel on Scientific Data and Information. 1 The free database currently contains about 5 700 ...
通常,电子光谱(UV-Vis、ECD)用高斯函数来展宽,振动光谱(红外、拉曼、VCD)用洛伦兹函数来展宽,洛伦兹函数衰减得比高斯函数要缓慢。Pseudo-Voigt函数则是高斯函数和洛伦兹函数的线性组合,组合系数是可调的。上面的公式中,ω就是光谱的横坐标,在给定了跃迁能量ω_i和FWHM之后,就立刻有了这个跃迁对应的吸收曲线的表达式。

Both UV-Vis and ECD are absorption spectra, commonly it is assume when a molecule undergo electronic excitation, the geometry is at minimum point of potential energy surface of ground state. Therefore, the ground state geometry should be optimized first. Since the conformational space of alanine ...
