Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 84(1), 196-209 (2011-10-14)
Experimental FTIR, FT-Raman and FT-NMR spectroscopic studies of o-fluoronitrobenzene and p-fluoronitrobenzene have been carried out. A detailed quantum chemical calculations have been performed using DFT/B3LYP method with 6-311++G** and 6-31G** basis sets. Complete vibrational analyses of the compounds were performed.

Analytical and bioanalytical chemistry, 410(14), 3349-3360 (2018-04-05)
Monitoring specific chemical properties is the key to chemical process control. Today, mainly optical online methods are applied, which require time- and cost-intensive calibration effort. NMR spectroscopy, with its advantage being a direct comparison method without need for calibration, has

Allergologia et immunopathologia, 14(6), 489-497 (1986-11-01)
The multi-functionality of a given antibody, even monoclonal antibody has recently been shown; this raises the possibility that the specificity of an antiserum be due to a population phenomena; i.e., the specificity would be the net result of the affinity

Membranes, 9(7) (2019-07-07)
Three new isomeric 6FDA-based polyimide-ionenes, with imidazolium moieties and varying regiochemistry (para-, meta-, and ortho- connectivity), and composites with three different ionic liquids (ILs) have been developed as gas separation membranes. The structural-property relationships and gas separation behaviors of the

FT-IR and FT-Raman spectra of p-fluoronitrobenzene (FNO(2)C(6)H(4)) have been recorded in the region 4000-100 cm(-1). In this work, the experimental and theoretical spectra of p-fluoronitrobenzene (p-FNBz) are studied. The molecular geometry and vibrational frequencies are calculated in the ground state

Organic & biomolecular chemistry, 8(12), 2823-2828 (2010-04-24)
A new series of enantiomerically pure 2,3,4,4a,5,6-hexahydro-1H-pyrazino[1,2-a]quinoxalines were synthesized for the first time in twelve steps from 1-fluoro-2-nitrobenzene and S-amino acids with 13-20% overall yields. First use of intramolecular Mitsunobu cyclization for 1,2,3,4-tetrahydroquinoxalines followed by PPh(3)/I(2)/imidazole mediated 6-exo-tet cyclization were

In the present investigation, the FT-IR/FT-Raman spectra of the m-fluoronitrobenzene (m-FNBZ) are recorded. The fundamental frequencies are assigned and the computational calculations are performed by DFT (B3LYP, B3PW91 and MPW1PW91) methods with 6-31++G(d,p) and 6-311++G(d,p) basis sets and the corresponding

We had previously shown that 4-fluoro-3-nitrophenyl azide (FNPA) is a competitive inhibitor of both types of monoamine oxidase (MAO) in the dark, but it is a preferential photoaffinity label for only the type B MAO (MAO-B). Recently we synthesized a
