| Popis: | Measurement of 1 H-15 N and 13 C-15 N coupling constants at natural abundance is demonstrated to be a reliable and generic method to determine the configuration of oximes, hydrazines, and related systems. Data on 1 H-15 N and 13 C-15 N coupling constants on a variety of systems obtained at natural abundance confirm the geometric dependence of the measured 1 H-15 N and 13 C-15 N coupling constants. In addition, we summarize a simple "decision-tree" for determining configuration based on practical considerations of sample quantity, solubility, and complexity.
