FIG. 1.

The iZQC-COSY sequence for high-resolution 2D COSY spectrum in inhomogeneous fields via 3D acquisition. Full vertical bars stand for nonselective rf pulses, Gauss-shaped pulses are spin-selective rf pulses, dash rectangles represent coherence selection gradients, “WS” represents the module of solvent suppression. The coherence transfer pathway is given and the raising and lowing operators are applied to show the coherence states of and spins.

2D absolute-value COSY spectra of a solution of butanone in cyclohexane: (a) conventional spectrum in the inhomogeneous field with a linewidth of 50 Hz; (b) iZQC-COSY projection spectrum in the same inhomogeneous field; (c) conventional spectrum in a well-shimmed field; (d) projection of iZQC-COSY simulative spectrum. The regions of the diagonal peak (I) and cross peak (II) in (b)–(d) were expanded for comparison.

FIG. 3.

2D absolute-value COSY spectra of a solution of n-butyl alcohol in DMSO in the inhomogeneous field with a linewidth of 50 Hz: (a) conventional spectrum; (b) iZQC-COSY projection spectrum. The regions labeled as (I), (II), (II), and (IV) were expanded for comparison.
