INVESTIGATIONS of the fluorescence spectra of polyatomic molecules in the vapour phase suffer from the obvious difficulty that a suitable exciting source is generally not available. For this reason the fluorescence spectra of a very few polyatomic molecules have been reported so far. In this direction...

Fluorochrome that binds to DNA and is used biochemically for detection of DNA and to stain the nucleus in fluorescence microscopy. dapper In Xenopus a protein (dapper-1, 824aa) that positively regulates dishevelled signalling pathways during development. Impedes the degradation of beta-catenin, there...
combination with 1-adamatanethiol (1-AdSH) as the HAT catalyst in the presence of formate catalyzed monoselective defluoroalkylation ofN-phenyltrifluoroacetamide with alkenes under irradiation with a 427 nm LED (Kessil®, emission FWHM of ~20 nm)35. A similar transformation was reported b...
In the predicted infrared spectrum of the dihydrogen-bonded phenol–TEGH complex, the OH stretching vibrational mode shifts to a lower frequency in the S1 state in comparison with that in ground state. The GeH stretching vibrational mode demonstrates a relatively smaller redshift than the OH ...

The S 1←S 0 00 0 transitions of phenol and the hydrogen bonded phenol(H2O)1 cluster have been studied by high resolution fluorescence excitation spectroscopy. All lines in the monomerspectrum are split by 56±4 MHz due to the internal rotation of the OH group about the a axis. The ...
,The concentrations of hydrogen peroxide (H2O2) and hydroxyl radical (HO·) in the catholyte were 8.3 mg/L and 2.15 μmol/L, respectively, which were determined by permanganate titration, electron spin resonance (ESR) spectrum and the fluorescence spectra. The efficiency of the removal of ...
The fluorescence excitation spectra and fluorescence lifetimes monitored on the 'red' and 'blue' wavelengths are equal. In a supersonic free jet the fluorescence occurs entirely from the keto form. Vibronic bands in the laser induced fluorescence (LIF) excitation spectrum are broad. The OH/OD ...
Red shift in UV-Vis spectrum at 210-220 nm and reduction of fluorescence emission intensity from tryptophan protein-like substances in EPS reduced the energy requirement for electrons transition of electron-donating groups with voltage increasing. Positively charged bond -NH2 decreased and negatively ...
