Proton multiple

Proton magnetic resonance (carbon tetrachloride) B (number of, protons, multiplicity) 3.63 (2, singlet), 3.48 (2, singlet), 3.27 (6, singlet). The infrared and mass spectra are also as reported. ... [Pg.43]

For twice-distilled material infrared (liquid film) cm." 1745 strong, 1565 strong, 1430 medium strong proton magnetic resonance (chloro-form-d) (number of protons, multiplicity, coupling constant J in Hz) 3.14-3.45 (1, multiplet), 3.76 (3, singlet), 3,86 (3, singlet), 5.6 (1, doublet of doublets, J = 6 and 8). [Pg.62]

Proton magnetic resonance (CDC13) 8, number of protons, multiplicity, coupling constant J in Hz. 1.5-2.2 (2, multiple ), 2.7-3.0 (4, multiplct), 7.0 (1, doublet, J = 2.5), 7.1-7.5 (6, multiplet), 7.7-8.2 (4, multiplet). A sample recrystallized from methanol-chloroform melted at 183-185°. The submitters also obtained pure product, m.p. 181-183°, after chromatography on basic alumina with 20% petroleum ether in dichloromethane as eluent. [Pg.12]

Distillation is unnecessary since the product is pure by spectral criteria. Infrared (liquid film) cm.-1 1730, 1555 proton magnetic resonance (CDCI3) 8, number of protons, multiplicity 1.30 (3, triplet, CH2C/73), 4.30 (2, quartet, Cf/2CH3), 4.8-5.2 (3, multiplet). [Pg.67]

Proton magnetic resonance (CDCla) 8, number of protons, multiplicity 2.25 (3, singlet, CH3), 7.27 (4, singlet, aryl CH), 7.33 (5, singlet, aryl CH) infrared (CHC13) cm.-1 1600 medium, 1480 medium strong (aromatic), 1380 medium (CH3). [Pg.86]

The method is more sensitive due to the higher proton multiplicity and is suitable for screening proteins up to 40kDa. The key binding site residues of a protein can be identified by using a known inhibitor to identify cross-peaks in the HSQC spectrum [38]. [Pg.19]

By application of proton multiple quantum (MQ) NMR experiments, information about the segmental order parameter, which is directly related to the restrictions on chain motion (cross-links) formed upon gelation of PVA, is obtained.103The quantitative study of rigid phase... [Pg.25]
