When the spectrometer is connected to the computer, the resulting calibration coefficients are saved in the spectrometer’s EEPROM to be read and applied. Users can check the accuracy of the wavelength calibration with suitable atomic emission sources. However, the actual calibration should only be c...
The two EELS spectra are normalized by their maximum counts for a better comparison. c FFT patterns obtained from different regions near the oxide. Full size image To better understand the reaction mechanism in aqueous corrosion, we performed thermodynamic calculations of the potential-pH diagrams ...
we perform first-principles calculations to determine the spin relaxation time (T1) and ensemble spin dephasing time (\({T}_{2}^{*}\)) in a prototype halide perovskite, CsPbBr3. To accurately capture
摘要: Tells which crystal to use for particular health or life issues, giving clear explanations of crystal related terms (such as phantom and record-keeper), how to choose a crystal that's been humanely mined, and read fascinating...
Raman measurements at 473.1nm on corals, both calcitic and aragonitic, and on pearls (aragonitic) were performed to elucidate the nature of the pigments, w... L Bergamonti,D Bersani,D Csermely,... - 《Spectroscopy Letters》 被引量: 41发表: 2011年 Effects of conjugation on the nπ* sta...
Spectra of different atoms Image credit: Marcel Patek. So with this basic issue underway, we next have the statement: "Atoms can only emit and absorb light of very specific frequencies, and hence we can observe absorption and emission lines unique to individual atoms." ...

If we take spectra ofquasars, some of the most luminous yet distant of astronomical objects, we can see the spectrum of hydrogen. But the emission lines are Doppler-shifted to redder colours (wavelengths) by the expanding universe. Hydrogen atoms produce a very distinctive spectrum of light. ...
