Study of structure and properties of platinum(II) chloride complexes with (2-alkyltetrazol-5-yl)acetic acid by quantum chemistry and NMR-spectroscopy methods

Журнал Белорусского государственного университета: Химия, 2019
It has been shown that the WP04 functional in combination with moderate basic sets 6-31G(d) and SDD allows to calculate characteristics of 1H NMR-spectrum of metal complexes with ligands based on tetrazole derivatives with high accuracy, which can be ...

NMRium: Teaching nuclear magnetic resonance spectra interpretation in an online platform

Beilstein Journal of Organic Chemistry
NMRium is the first web-based software that allows displaying, processing, interpretation, and teaching of 1D and 2D NMR data in a user-friendly interface. It can import the most common data formats (e.g., JCAMP-DX, Bruker, Varian, and Jeol).

NMR spectra interpretation

, 2014
Introduction: From all the methods, nuclear magnetic resonance NMR is one that offers the richest and the most complete structural information about organic compounds. This method can be applied to the elucidation o f chemical structure as well as the determination o f stereochemistry and conformation o f their pure substance and mixture.

Distinguishing Rock Fracture and Pore's T2 Signals From NMR Experiments With Assisted X‐Ray CT Imaging

Energy Science & Engineering
Nuclear magnetic resonance (NMR) is widely used to characterize fluids in rock pore spaces, but traditional methods have difficulty distinguishing fractures from matrix pores in complex carbonate formations.

Effect of the Internal Magnetic Field Gradient on Two Dimensional NMR Responses in Volcanic Rock

Cejing jishu
Two dimensional (2D) nuclear magnetic resonance (NMR) technology can provide two kinds of relaxation information simultaneously, which has significant advantages in fluid identification and quantitative evaluation. There are rich paramagnetic minerals in

New methods for NMR spectral analysis

Journal of Analytical Science and Technology, 2011
A set of novel methods for signal enhancement and artifact suppression in multidimensional NMR spectra have been developed. These methods, independent of the experiment type, aim at improvising resonance assignments, accurate measurement of NMR ...
