在定量H-1 NMR谱内给定C-12-H-1母体共振的C-13-H-1卫星峰的积分和与次要组分的比较代表了用于精确测定高达1000:1的非对映异构体比率(即,99.8% de)。
Integration of a C-13-H-1 satellite peak of a given C-12-H-1 parent resonance within a quantitative H-1 NMR spectrum and comparison to the minor component represents a simple protocol for the accurate determination of diastereoisomeric ratios of up to 1000:1 (i.e., 99.8% de).
