Methylaminodiphenylborane — Application of nB, 13C, 14N, 15N NMR
نویسنده
چکیده
UB, 13C, 14N, 15N NM R is used to study methylaminodiphenylborane (1). Compound 1 can be regarded as a model compound for studying BN(pp)jr-, B C (pp)7r interactions, for determining the barrier to rotation about the B —N bond and for the application of natural abundance 15N NM R to boron-nitrogen chemistry. The 13C NM R of 1 shows a large splitting of the uC (para) resonances (in contrast to reports on similar compounds in the literature) as a consequence o f hindered rotation about the BN bond. The difference in the n C (para) nuclear shielding indicates different mesomeric interactions between the trigonal boron atom and the two phenyl groups.

Measuring amide nitrogen quadrupolar coupling by high-resolution 14N/13C NMR correlation under magic-angle spinning.
The measurement of amide nitrogen 14N quadrupolar coupling by two-dimensional 14N/13C correlation experiment is presented with a natural abundant polypeptide. Directly bonded 14N/13C pairs are correlated through J and residual dipolar coupling under magic-angle spinning using a HMQC-type pulse sequence. The 14N quadrupolar coupling is measured from the isotropic second-order quadrupolar shift o...
متن کاملThe Titan 14N/15N and 12C/13C isotopic ratios in HCN from Cassini/CIRS
We report the detection of H13CN and HC15N in mid-infrared spectra recorded by the Composite Infrared Spectrometer (CIRS) aboard Cassini, along with the determination of the 12C/13C and 14N/15N isotopic ratios. We analyzed two sets of limb spectra recorded near 13–15◦ S (Tb flyby) and 83◦ N (T4 flyby) at 0.5 cm−1 resolution. The spectral range 1210–1310 cm−1 was used to retrieve the temperature...

In this paper, the hydrogen bonding (HB) effects on the NMR chemical shifts of selected atoms in serineand serine-nH2O complexes (from one to ten water molecules) have been investigated with quantummechanical calculations of the 15N and 13C tensors. Interaction with water molecules causes importantchanges in geometry and electronic structure of serine.For the compound studied, the most importan...
متن کامل3D NMR experiments for measuring 15N relaxation data of large proteins: application to the 44 kDa ectodomain of SIV gp41.
A suite of 3D NMR experiments for measuring 15N-¿1H¿ NOE, 15N T1, and 15N T1rho values in large proteins, uniformly labeled with 15N and 13C, is presented. These experiments are designed for proteins that exhibit extensive spectral overlap in the 2D 1H-15N HSQC spectrum. The pulse sequences are readily applicable to perdeuterated samples, which increases the spectral resolution and signal-to-no...
متن کاملObservations of nitrogen isotope fractionation in deeply embedded protostars.
CONTEXT The terrestrial planets, comets, and meteorites are significantly enriched in 15N compared to the Sun and Jupiter. While the solar and jovian nitrogen isotope ratio is believed to represent the composition of the protosolar nebula, a still unidentified process has caused 15N-enrichment in the solids. Several mechanisms have been proposed to explain the variations, including chemical fra...
