1’000 scientific publications. EasyDirect UV/VIS offers direct data exchange with this powerful tool: Simply select one or more spectra from the list of stored spectra in the EasyDirect database, and with a single mouse click, you are set to compare and/or analyze them further in ...
The fundamental initial step of photochemical reactivity is absorption of a photon; however, little guidance has been provided thus far regarding how ultraviolet–visible (UV–vis) light absorption spectra may be used to inform testing strategies for investigational drugs. Here we report the results ...
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. ...
Fourier transform infrared and Raman spectra of trimetazidine (TMZ) were recorded. The structure, geometry optimisation and vibrational frequencies were investigated. The specific mode of normal coordinate analysis was made for the stable conformer of the molecule using restricted Hartree–Fock (RHF) and...
LabX® UV/VIS PC software expands the instrument with a sophisticated graphical editor for spectra evaluation. Data Analysis and management are simplified in one FDA 21 CFR part 11 / EU annex 11 compliant software package. To optimize and secure your workflow even better, let the task schedule...
TDDFT prediction of UV–vis absorption and emission spectra of tocopherols in different media 来自 国家科技图书文献中心 喜欢 0 阅读量: 24 摘要: We use the TDDFT/PBE0/6-31+G* method to determine the electronic absorption and emission energies, in different media, of the four forms of ...
In the present work ultraviolet (UV)-visible spectra of water samples collected at the outlet of a fuel park wastewater treatment plant, including biological treatment, were acquired and used for the development of partial least squares (PLS) calibration models for the fast and simple estimation of...
