摘要:... The theory, which takes into account the effect of dynamic disordering in one-dimensional molecular systems, explains the experimentally measured features of the difference absorption spectra for PIC Cl J-aggregates fairly well. Specifically, the ‘blue-shifted’ spectral ...

摘要:... Magnitudes of binding constant and related Gibbs free energies were optimized using differential absorption spectrometry and micellar liquid chromatography (MLC). The results indicate potential solubilization of drugs in the peripheral region of micelles that may be helpful t...

摘要:Abstract(#br)Detection of ammonia (NH 3 ) concentration plays an important role in monitoring and controlling air pollutants. However, the existing NH 3 detection methods do not conform to current needs. A low-cost and easily-realized gas sensing system for NH 3 detection is deve...

摘要:... Transient differential absorption measurements have been employed to investigate the ultrafast relaxation dynamics of photogenerated carriers in the SnO 2 NWs. Steady state transmission measurements revealed that the band gap of these NWs is 3.77 eV and contains two broad absorption...

摘要:Abstract(#br)It is found that, with the action of photoexcitation and a variable magnetic field on halide-containing porphyrin solutions, a differential absorption is observed, whose spectra conform to the absorption spectra of cation radicals of pigments. It is shown that the e...

摘要:... We apply the derived formulas for calculating the differential absorption spectrum of quantum-well samples under excitation conditions supporting the slow exciton–exciton scattering. The obtained results are in good qualitative agreement with available experimental observa...

摘要:... The sensor adopts the long optical path differential absorption spectroscopy technique (LOP-DAST) and obtains minimum detection limit (MDL) of 108 ppbv by comparing the residual difference between the measured spectrum and the Voigt theoretical spectrum. As a comparison, t...
