摘要

concentration in moles per liter. proximate line width is in parts per million at 13.5 MHz. for nonequivalent doubly bridging oxygens in 7 and 8 to be resolved. The quadruply bridging oxygen resonance for 8 was not observed due to lack of enrichment at this site. Examination of Figure 2 in its entirety confirms the correlation between upfield shift and increasing degree of bridging noted earlier. Moreover, the clustering of chemical shifts within the 0-Mo and O ...
