“…One disadvantage to this method is that the cross-peak and diagonal peak intensities need to be measurable. Errors in these measurements are propagated into the rate calculations . Another disadvantage is that several mixing times must be used, leading to the need for large amounts of instrument time .…”

Kinetics and Mechanism of the Stereochemical Isomerization of an Arene−Ruthenium Complex of the Atropisomeric Ligand 1,1‘-Biphenyl-2,2‘-diamine

(η6-Benzene)(δ/λ-1,1‘-biphenyl-2,2‘-diamine)chlorometal(II) hexafluorophosphate (1; metal = ruthenium, osmium) have been synthesized. The rigid nature of the seven-membered chelate ring formed by the 1,1‘-biphenyl-2,2‘-diamine (dabp) ligand renders the complexes chiral. The resulting C 1 molecular symmetry of 1(M=Ru) that we have observed in the solid state by single-crystal X-ray crystallography is preserved in solution on the NMR time scale. The four N−H protons of 1(M=Ru,Os) are chemically inequivalent in the 1H NMR spectrum at 20 °C. Spin-perturbation NMR experiments in acetone solutions reveal pairwise exchange of the resonances that correspond to the N−H protons on the spin-relaxation time scale. The three mechanisms that would account for such an exchange (atropisomerization of the dabp ligand, inversion of stereochemistry at the metal center, and simultaneous inversion of the stereochemistry at the metal and the ligand) are distinguishable, provided a proper assignment of the four N−H protons can be made in the NMR spectra. Having made that assignment, we conclude from 2D EXSY NMR spectroscopy that the mechanism of exchange is inversion of stereochemistry at the dabp ligand center. This observation contrasts with previous reports that conformational isomers of dabp can be resolved.

“…33 NOE build-up curves were constructed using the PANIC approach. 34,35 In the 1D DPFGSE 1 H, 1 H-T-ROESY spectra, each NOE enhancement was normalized with respect to the target signal in the same spectrum. In 2D 1 H, 13 C-HSQC-NOESY spectra, each NOE cross-peak intensity was normalized with respect to the average intensity of the two diagonal signals (intramolecular Man 3 NOEs) or the Man 3 diagonal signal intensity (intermolecular NOEs) in the same spectrum.…”

Exploiting Uniformly ¹³C-Labeled Carbohydrates for Probing Carbohydrate–Protein Interactions by NMR Spectroscopy

et al. 2017

NMR of a uniformly 13C-labeled carbohydrate was used to elucidate the atomic details of a sugar-protein complex. The structure of the 13C-labeled Manα(1–2)Manα(1–2)ManαOMe trisaccharide ligand when bound to cyanovirin-N was characterized and revealed that in the complex the glycosidic linkage torsion angles between the two reducing-end mannoses are different from the free trisaccharide. Distances within the carbohydrate were employed for conformational analysis, and NOE-based distance mapping between sugar and protein revealed that Manα(1–2)Manα(1–2)ManαOMe is bound more intimately with its two reducing-end mannoses into the domain A binding site of CV-N than with the non-reducing end unit. Taking advantage of the 13C spectral dispersion of 13C-labeled carbohydrates in isotope-filtered experiments is a versatile means for a simultaneous mapping of the binding interactions on both, the carbohydrate and the protein.

“…The manual of the test (Schutz, 1988) reports numerous concurrent validity studies, but relatively few construct validity studies. Various reviewers have sought to discover the concurrent validity or overlap between the FIRO‐B and other measures like field dependence (McRae & Young, 1990), adaptive‐innovative cognitive style (Tullett & Davies, 1999) and team role preferences (Fisher, Macrosson, & Semple, 2001). However, this research effort has been piecemeal and non‐systematic.…”

This paper investigated the relationship between the six Fundamental InterpersonalRelations Orientation (FIRO)-B scales, the Big Five Personality traits assessed by the NEO PI-R, the Hogan Development Survey (HDS) and two measures of cognitive ability (Watson Glaser; Graduate and Managerial Assessment). It examined the concurrent and construct validity of the measure in various adult groups attending assessment centres in order to locate the FIRO-B dimensions in established personality factor space. The FIRO-B was consistently correlated with Extraversion, though analysis at the primary factor (facet) level showed many traits from all five factors were strongly correlated with the six FIRO-B scores. Regressing the six FIRO-B facets onto each of the Big Five in turn showed all were significant particularly for Expressed Inclusion and Wanted Control. The second study also showed considerable and logical overlap between the six FIRO-B scales and the 11 dysfunctional personality strategies as measured by the HDS. There were also strong correlational patterns for the Cautious, Reserved, Colourful and Dutiful type disorders. The third study showed the FIRO-B was statistically associated with both cognitive ability tests though it only accounted for small percentages of the explained variance. Expressed Control was the most consistently correlated of the intelligence test scores. Despite the fact that many explicable associations were found between the FIRO-B and other measure the effect sizes were not large. Thus only 4% of the trait facet scores and 4.5% of the HDS showed medium effect sizes. Results are discussed in terms of the usefulness and possible discriminant validity of the instrument for use in selection and assessment.
