The spectrum also showed, between the most significant signals, a singlet integrating for 3 protons at δ 3.57 assigned to the methoxy group at C-2, a doublet of triplets at δ 3.05, assigned to H-12α...Antonio Evidente, Amina H Abou-Donia, Fikria A Darwish, et al. Nobilisitine A...
Similarly, signals from the olefinic hydrogens in the HCC-ring that appear in the salicortin 1H-NMR spectrum at δ6.27 and δ5.76 each as a doublet of triplets, were absent. In 3 these signals were replaced by four separate olefin signals between δ6.60 and 5.85 each integrating for one...

Doublets and triplets are two major types of multiplets, with the former representing two cells captured together (the dominant case) and the latter representing three cells captured together (the less common case). While the terms “doublet” and “multiplet” are used interchangeably in most ...
The two doublet histones of Marseillevirus are distantly related to the four eukaryotic core histones and wrap 121 base pairs of DNA to form remarkably similar nucleosomes. By permeabilizing Marseillevirus virions and performing genome-wide nuclease digestion, chemical cleavage, and mass spectrometry...

General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We discuss
当出现多重峰的时候,将使用下面的缩写:s(singlet,单峰)、d(doublet,双峰)、t(triplet,三重峰)、m(multiplet,多重峰)、br(broadened,宽峰)、dd(doubletofdoublets,双二重峰)、dt(doubletoftriplets,双三重峰)。偶合常数j,单位用赫兹(hz)表示。低分辨率质谱(ms)数据的测定条件是:agilent6120四级杆hplc-ms(...
Data are reported as follows: chemical shifts (ppm), multiplicity (s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, dd = doublet of doublets, ddd = doublet of doublet of doublets, dt = doublet of triplets, dq = doublet of quartets, dqd = doublet of ...
For the j=1/2 doublet, the calculated decay widths are rather broad with the current mass predictions of initial and final states, which agree with the calculations in the quark pair creation model [71]. For the j=3/2 triplet, the predicted decay widths are about 65, 75, and 92 MeV...
