The IR spectra of nitrobenzene-d0 and -d5 were recorded in gas and liquid phases at 25°C and in amorphous solid phase at -170°C. The appearance of new bands and intensity changes going from liquid to solid phase spectrum, are interpreted in terms of molecular symmetry modifications. A ...
The radical anion of nitrobenzene is prepared by reacting atomic sodium with nitrobenzene in a nitrobenzene matrix at 77°K. For the first time, the complete IR spectrum of the crystalline nitrobenzene radical anion has been measured in the 400–3800 cm 1 range....

The OH stretching frequency of the CO complex is 26 cm-1 red shifted from that of the monomer in the IR dip spectrum, but the N2 complex shows no shift. On the basis of these findings we conclude that carbon monoxide is bonded to the OH group via a hydrogen bond, whereas nitrogen is...
摘要: FT-IR and FT-Raman spectra of Vitamin c have been recorded and analysed. SERS spectrum was recorded is silver colloid. The molecule is thought to adsorb with the lactone ring in a tilted side on orientation with respect to the silver surface....
ft-ir and ft-raman spectra of 2-(methoxycarbonylmethylsulfanyl)-3,5-dinitrobenzenecarboxylic acid were recorded and analyzed. surface enhanced raman scattering (sers) spectrum was recorded on a silver colloid. the vibrational wavenumbers were computed by density functional theoretical (dft) ...
The bands due to the stretching modes CO, CS and SO2 are intense in the SERS spectrum. The CH stretching mode also appears in the SERS spectrum. The molecule is found to adsorb through both the carboxyl and sulphonyl groups. A possible tilted orientation of the molecule is suggested. ...
