WebDescription: A triplet of doublets (td) is a pattern of three doublets, in a 1:2:1 ratio of relative intensities, that results from coupling to two protons (or other spin 1/2 nuclei) with a larger J value and one proton (or other spin 1/2 nucleus) with a smaller J value. Example: td, J = 10, 3 Hz 10 Hz 10 Hz 3 Hz 3 Hz 3 Hz WebThe spectrum of ethyl chlorideconsists of a triplet at 1.5 ppm and a quartet at 3.5 ppm in a 3:2 ratio. The spectrum of benzeneconsists of a single peak at 7.2 ppm due to the diamagnetic ring current. Together with carbon-13 NMR, proton NMR is a powerful tool for molecular structure characterization.

WebAug 25, 2024 · What is a quartet of triplets? THEORY: When there are two sets of adjacent H atoms, the number of peaks multiply. For example, a CH2 group with a CH2 group and a CH3 group on either side should show 3 x 4 = 12 peaks for its signal! You can say this group is a “triplet of quartets” (or a “quartet of triplets”).
