Carbon-13 Chemical-Shift Tensors in Polycyclic
The principal values of the 13C chemical-shift tensors of natural abundance biphenylene were measured at room temperature with the FIREMAT experiment. Of 18 crystallographically distinct positions (three sets of six congruent carbons each), the three primary bands have been resolved into seven single peaks and four degenerate peaks (two double, one triple, and one quadruple). Hence, eleven diff...
متن کاملEchoplanar chemical shift imaging.
A novel method of chemical shift imaging utilizing echoplanar imaging (EPI) has been developed for the purpose of improving the spatial resolution of metabolite images for the specific goal of high spatial resolution mapping of neuronal content. An EPI sequence was modified to allow temporal offsets of the 180 degree refocusing pulse that encode the chemical shift information into the phase of ...
متن کاملCarbon-13 chemical shift anisotropy in DNA bases from field dependence of solution NMR relaxation rates.
Knowledge of (13)C chemical shift anisotropy (CSA) in nucleotide bases is important for the interpretation of solution-state NMR relaxation data in terms of local dynamic properties of DNA and RNA. Accurate knowledge of the CSA becomes particularly important at high magnetic fields, prerequisite for adequate spectral resolution in larger oligonucleotides. Measurement of (13)C relaxation rates o...
متن کاملMetathesis Activity Encoded in the Metallacyclobutane Carbon-13 NMR Chemical Shift Tensors
Metallacyclobutanes are an important class of organometallic intermediates, due to their role in olefin metathesis. They can have either planar or puckered rings associated with characteristic chemical and physical properties. Metathesis active metallacyclobutanes have short M-Cα/α' and M···Cβ distances, long Cα/α'-Cβ bond length, and isotropic 13C chemical shifts for both early d0 and late d4 ...
متن کاملNa Chemical Shift Imaging of myocardial edema
Introduction – Distinction between viable and non-viable myocardium is essential for diagnosis and treatment of patients with coronary artery disease. Delayed contrast-enhanced (DCE) MRI has become the gold standard to determine the size of chronic infarcts. However, although T2-weigthed MRI shows great promise to delineate the area at risk after the event related to the formation of edema, the...
