摘要：

The improved understanding and control of induced eddy current effects has led to the increased application of pulsed field gradients in high-resolution 2D NMR spectroscopy. Of particular interest is the ability to select specific coherences in a single acquisition with concomitant "quadrature detection" in the F1 dimension. A product-operator analysis of this effect for an AX spin system which describes the selection of N-type or P-type signals using appropriate gradient episodes in the COSY and 2D double-quantum experiments is presented. © 1991.
