An assignment of 13 of the 15 infrared active vibrations of both molecules has been made. The assumption that s-trinitrobenzene is planar with D3h symmetry is supported by the analysis of the infrared spectrum. Vibrations involving the nitro groups are virtually unchanged upon deuteration of s-...

They subtracted the spectrum of the glass fibres from the spectra of the flat and fractured surfaces to remove the spectral contributions from the glass. They then isolated the spectral effects of the interface by subtracting the flat-surface spectrum from the fractured-surface spectrum. They found...
However, the low photon energy of NIR light usually cannot meet the direct activation threshold of the commonly used PPGs, such as PPGs based on nitrobenzene8, coumarin9,10,11 and boron-dipyrromethene (BODIPY)12. There have been strategies to achieve long-wavelength light-triggered prodrug ...
The bands at -3109, -1600, ~1520,-1350, -850, -825 and -744 cm-1 result from p-nitrobenzene of the porphyrin. Metal sensitive bands were found at -1489, -1076, -737 and -245 cm-1. 展开 关键词: Porphyrin Transitional metal Infrared photoacoustic spectra ...

The infrared spectrum of a mineral is a characteristic feature, which permits the identification of mineral species. The absorption bands arise from vibrations of the atoms or ions in the structure, and the frequencies of vibrations are dependent on the mass of the atoms, the restraining forces ...

The spectrum of nitrobenzeneA simple laboratory method for the preparation of perdeuterated polyethylene sheets from powder is described. These sheets have been used as matrix material to obtain polarized IR spectra by ...
about 49 per cent C 6H 5N 16O 18O, 32 per cent C 6H 5N 16O 2 and 19 per cent C 6H 5N 16O 2 was measured, in solution in carbon disulphide or carbon tetrachloride or as a liquid, in the 3700–390 cm 1 region, in comparison to the corresponding spectrum of normal nitrobenzene....
