Iron is one of the most abundant heavy elements in the universe. Its spectral features stand out in many astronomical spectra, especially in those of stars and galaxies. As a dominant emitter in many ...

The individual absorption spectra of the two NH tautomers of 10-(4,6-dichloropyrimidin-5-yl)-5,15-dimesitylcorrole are assigned on the basis of the Gouterman four-orbital model and a quantum chemical ...

WEST BEND, Wis. — The Wisconsin Department of Agriculture, Trade and Consumer Protection is in its third year of the Nitrogen Optimization Pilot Program(NOPP) to make sure soil is in the best shape it ...

Yet the broader regions of absorption, which can be difficult to observe with the spectroscope, often have a greater influence on a diamond’s color. A chart has been prepared to illustrate the visible ...

The interaction site of phthalocyanine (Pc) with nitrogen dioxide (NO2) has been characterized using different methods and found to be conflicting. By knowing the interaction site, the Pc molecule can ...

Its absolute density is measured in specific operating conditions by Vacuum UltraViolet (VUV) absorption spectroscopy using a highresolution Fourier Transform Spectrometer (FTS). The uncertainty of ...
