摘要

Figure 3. Diisopropyl-do D-tartrate (5096) and diisopropyl-dl6 L-tartrate (50%) calculated (b) and found (a). mass spectrometry, as dimethyl tartrate3 shows in a striking manner (Figure 1). With a mixture of 10% dimethyl-d6 D-tartrate (MH+ 185) and 90% dimethyl-do L-tartrate (MH+ 179) in the direct insertion probe, the excess optically active form preferentially evaporates, and the spectrum, corrected for incomplete deuteration, gradually approaches ...
