Abstract The furanose 1 H NMR resonances of cyclobutadi-2′-deoxyuridine were examined by both one-dimensional and two-dimensional (two-dimensional J and two-dimensional J connectivity)… (More)
In order to obtain information about the conformational characteristics at the nearestneighbor level in the 2′-O-methylated region of t-RNA, as well as in the bizarre 5′-terminus of eucaryotic mRNA,… (More)
This NMR study on short DNA helices has five general objectives: (1) to develop effective approaches in the assignment of proton and phosphorus resonances of short helices; (2) to calibrate the NMR… (More)
Two short DNA helices, d-(CpGpCpG)2 and d-(CpGpCpGpCpG)2, in dilute salt solutions have been studied thoroughly by 1H- and 31P-nmr spectroscopy as model systems for the calibration of nmr theory in… (More)
The assignments of 31P resonances of eight short oligonucleotides have been achieved through specific heterodecoupling techniques reported previously from our laboratory [Cheng et al. (1982)… (More)
Abstract The 1H-NMR results show that the majority of the isoprene units of butyl rubber are incorporated in 1,4 addition. Approximately 6% of the isoprene units undergo 1,2 enchainment. Based on our… (More)
