Fig 3.
Part of a two-dimensional 1H,13C HSQC spectrum of CDP-d-arabinitol. The corresponding part of the 1H NMR spectrum is displayed along the horizontal axis. Arabic numerals refer to cross-peaks in the ribose, arabinitol, and cytosine moieties, designated R, A, and C, respectively. Signals of CMP and glycerol contaminants are marked with an asterisk. The structure of CDP-d-arabinitol is shown in the inset. HDO, hydrogen deuterium oxide.
