Answer to Question #224993 in Organic Chemistry for Johnny haobam

Question

define spin-spin coupling of NMR using 1,1- dichloroethane

Answer 1

Spin-spin coupling is the interaction between the spin magnetic moments of different electrons and/or nuclei. In NMR spectroscopy it gives rise to multiplet patterns, and cross-peaks in two-dimensional NMR spectra. Between electron and nuclear spins this is termed the nuclear hyperfine interaction.

1,1-dichloroethane has 1,1-DICHLOROETHANE(75-34-3) 1H NMR. NMR signals
