Carboxylic acids are ubiquitous in bioactive organic molecules and readily available chemical building blocks. Carboxylic ...

Hydrogen bonding is often the driving force in determining how organic molecules do differ in their methods of "3D packing" forming polymorphs or pseudo-polymorphs (pseudo-polymorphism referring ...

This structure makes protein-based materials as strong as steel, even though the hydrogen bonds that hold them together are 100 to 1,000 times weaker than the metallic bonds in steel.

The δ H 0.73 peak combines for six protons and is observed to be a doublet implying that it bonds with the proton at δ H 2.13. There are now 2 carbon atoms and 6 hydrogen atoms, with a CH group and a ...

The theoretical values in 1-octene and undecane were compared to their hydrogen content as determined from Equation (1) and using the integration regions for I (Sample) that are highlighted in Figure ...

Hydrogen consumption presents a significant cost issue in a refinery, ... ASTM* D 7171 is an International Standard Method based on Pulsed TD-NMR. Hydrogen content by TD-NMR. QA/QC measurement; ...
