spin coupling वाक्य

उदाहरण वाक्य

1. As these metals go superconducting, electrons with oppositely directed spins couple to form singlet states.
2. Another characteristic of Roberts'work was the early use of NMR, the concept of spin-spin coupling.
3. The spin spin coupling between nonbonded atoms in close proximity has sometimes been observed between fluorine, nitrogen, carbon, silicon and phosphorus atoms.
4. Substantial shifts occur upon complexation and 31 P-31 P spin-spin coupling can provide insight into the structure of complexes containing multiple phosphine ligands.
5. Proton NMR spectra of most organic compounds are characterized by chemical shifts in the range + 14 to-4 ppm and by spin-spin coupling between protons.
6. Spin-spin coupling is observed in NMR of hydrogen-1 ( NMR ), since its natural abundance is nearly 100 %; isotope enrichment is required for most other elements.
7. Unlike spin-spin coupling, NOE propagates through space and does not require that the atoms are connected by bonds, so it is a true distance measurement instead of a chemical measurement.
8. Some of her results include the complex role of the valley interference in the spin coupling of pairs of donors in silicon and the mechanisms for controlling the valley degree of freedom in silicon.
9. Carbon-13 NMR overcomes this disadvantage by larger range of chemical shifts and special techniques allowing to block carbon-proton spin coupling, thus making all carbon signals high and narrow singlets distinguishable from each other.
10. In addition, two hydrogen nuclei can interact via a process known as spin-spin coupling, if they are on the same molecule, which will split the lines of the spectra in a recognizable way.
