Phasing and Zero Referencing

7-6 Two-Dimensional NMR Data Display 7-6a Phasing and Zero Referencing 

To correct the phase and zero reference of diagonal and cross peaks along the v axis, the contour plot is rotated by 90° so that v is the horizontal axis. Signals at each end of the vi axis then are selected, phased, and checked for zero referencing, as was done for V2-Finally, by convention, contour plots are presented so that the detected (02) dimension is along the horizontal axis and the nondetected (vi) dimension is along the vertical axis.
