This chapter tabulates the functional groups for UV–Vis spectroscopy, their molecular structure, relative band intensities, primary band, and secondary band. Various functional groups such as alcohols, ethers, thiols, alkenes, acetylenes, nitriles, azo compounds, nitrates, and aldehydes are discussed...
in the transmission mode in methanol solutions, in the spectral range 300–800 nm, at 2 nm spectral resolution. Data were converted to the absorbance scale. Characteristic absorption bands for the three dyes are, respectively, at around: 492 nm and 524 nm, for cyanine iodide; 604...
(750 – 1100 nm) light giving a total wavelength coverage of 190-1100 nm. There are two main types of UV-Vis spectrometers single-beam and double-beam. In single-beam spectrophotometers, there is only one light path, and manual switching of the sample and reference cuvettes is required. ...
One (in the range 400-650 nm) originates from dissociation of the 3s and 3p Rydberg states, whilst the other (in the range 250-500 nm) originates from higher members of the s, p and d Rydberg series. The emitting states in BCl+3 are the D 2E' and E 2A'1 states with adiabatic...
UV/VIS/NIR Spectroscopy is used to determine analyte concentration by measuring light absorption across the ultraviolet and visible light wavelengths.
Abundances of a range of air pollutants can be inferred from satellite UV-Vis spectroscopy measurements by using the unique absorption signatures of gas species. Here, we implemented several spectral fitting methods to retrieve tropospheric NO2, SO2, and HCHO from the ozone monitoring instrument (OMI...
Deep-UV (DUV) laser patterning has been widely used in recent years for micro- and nanopatterning, taking advantage of the specific properties of irradiation with high-energy photons. In this paper, we show the usefulness of DUV laser patterning for prep
