Triplet of doublet
WebIn the spectrum of 1,1,3-trichloropropane, for example, we would expect the signal for H b to be split into a triplet by H a, and again into doublets by H c, resulting in a ‘triplet of doublets’. H a and H c are not equivalent (their chemical shifts are different), but it turns out that 3 J ab is very close to 3 J bc . WebApr 11, 2024 · We previously performed a systematic review and network meta-analysis (NMA) on the role of triplet therapy versus different doublet therapies in mHSPC, but …
