XEASY Peak List

Peak List

The XEASY peak list contains the peak number, chemical shift in dimension 1 and 2, peak color, peak volume, volume error, and the atom numbers in dimension 1 and 2, plus some unused information (i.e., "U", "-", and "0"). Shown below is a section of a 2D [15N, 1H]-HSQC peak list. Extension to 3D and 4D experiments is achieved by adding additional chemical shift and atom number columns.
