摘要: A heteronuclear multiple quantum correlation (HMQC) experiment was used to correlate the 6Li and 15N chemical shifts of mixed aggregates [6Li, 15N]lithium 2,2,6,6-tetramethylpiperidide with [6Li]LiBr, [6Li]LiCl, [6Li]lithium cyclohexenolate. Optimization spin systems containing more than one weak is discussed. The two-dimensional correlations represent a substantial improvement in sensitivity resolution relative one-dimensional methods.
