We used F-terminated telechelic oligomer as the model oligomer for the NMR assignment of the SABC. The chemical structure of the model oligomer is also shown in Figure 1. The solvent and the ...

NMR can be used for the quantification of minute quantities (mg to mg) of standard compounds. The high specificity of NMR signals permits absolute quantifications independent of the presence of ...

Most students know about aspirin, a pain-relieving compound, and they gain knowledge about the role of chemistry in real-life applications from its synthesis. It is possible to perform aspirin ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

There are federal training requirements about the dangers of the NMR magnets and the danger of helium asphyxiation that need to be taught to anybody entering the NMR room PS13. Unauthorized persons ...

Acetylacetone (2,4-pentanedione) is a β-diketone that occurs in the form of enol and tautomeric keto mixture. In basic solution, this organic compound is deprotonated to form the acac or ...

The technique in this article explores applied radio frequency fields B 1 expressed and employed as nutation frequencies for nucleus i,ƒ (1,i) =1/2π |1/2 γ i B r,i |, vital constraints in solid-state ...
