spin spin coupling
How peaks in a proton NMR can get split into multiplets due to coupling with neighboring protons. , The source of signal splitting is a phenomenon called spin-spin coupling, a term that describes the magnetic interactions between neighboring, non-equivalent NMR-active nuclei. In our 1,1,2 trichloromethane example, the Ha and Hb protons are spin-coupled,Introduction to Spin-Spin Coupling in H-NMR. Recall that protons have a magnetic field associated with them (since they have a nuclear spin), and when they are placed in a magnetic field approximately half of the protons become aligned with the field and ,Donate here: http://www.aklectures.com/donate.php Website video link: http://www.aklectures.com/lecture ... ,Donate here: http://www.aklectures.com/donate.php Website video link: http://www.aklectures.com/lecture ... ,Indirect spin-spin coupling (indirect dipole-dipole interaction, J-coupling) - a magnetic interaction between individual nuclear spins transmitted by the bonding electrons through which the nuclear spins are indirectly connected. Chemically and magnetical, For the Fermi contact mechanism of spin-spin coupling (there are other mechanisms), the bonding electrons for a H-13C fragment will become polarized as shown, so that the more stable orientation of the 13C-nucleus will be down, when the proton is up.
