Later, all compounds were analyzed by [1] HNMR and IR spectroscopy, as well as by GCMS confirming the diacid as our final compound.
to A.P., for further analysis (Orlandi, 1994) by Hnmr spectroscopy.
Solid phase CNMR and HNMR studies were performed to determine the carbon of carbonyl and proton of carboxylic acid made on the surface of SWCNT.
Glycerol/starch/Na+montmorillonitenanocomposite: XRD, FTIR, DSC and HNMR study.
The fraction eluted with 5% ethylacetate in hexane gave pure BPNE (0.75g), Rf 0.38, (1) HNMR ([CDCI.sub.3], 200 MHz) [delta] 3.3, t, 2H; 4.6, t, 21-1; 7.3, m, 5H, (13) C NMR ([CDCI.sub.3], 50MHZ) [delta]136.0, C-1; 129.2 x 2, C-3 and C-5; 128.9 x 2, C-2 and C-6; 127.7,C-4; 76.5,0-12: 33.6, [CH.sub.2]), ElMS m/z 104 (100%) (loss of [HNO.sub.2]), 99.2% pure (GC).
In the present study a novel series of tetrahydroquinoline were synthesized and characterized by means of IR, 'HNMR, 13CNMR, Mass spectral analysis and elemental analysis.
'HNMR and [sup.13]C NMR spectra were measured at room temperature on a 400 MHz (Bruker) spectrometers, respectively, using DMSO-d6 or CD[Cl.sub.3] as the solvents.
The complexes were characterized on the bases of their molar conductance, IR, UV-Vis, and (1) HNMR spectral studies.
HNMR (300 MHz, DMSO-d6): 6.83 (s, NH, 2H), 7.03 (2H,d, J = 8.4 Hz), 7.35 (s, 1H), 7.56-7.71 (m, 2H) , 7.97 (d, J = 8.4 Hz, 2H), 15.47 (br s, OH).
HNMR spectroscopy was used to confirm the structures of synthesized ILs and for this [sup.1]HNMR (Bruker Avance 300 MHZ) spectroscopy in [D.sub.2]O was used, while a CHNS-932 (LECO) apparatus was used for the elemental analysis.
