Setting the Number of Points to Acquire in a 2-D Spectrum

12 Hz/pt (less than the 1.15 Hz splitting). Notice that the middle trace (0.28 Hz/pt) already shows a noticeable connect-the-dots quality and that further reductions in the number of points per unit frequency dramatically degrade the symmetry of the multiplet. 

Data point. Two numerical values (i.e., an x, y pair) corresponding to intensity as a function of time, or to intensity as a function of frequency. 

Triplet. Three evenly spaced peaks in the frequency spectrum caused by the splitting of a single resonance by J-coupling to two identical spin-V2 nuclei to give a multiplet with three peaks with relative intensity ratios of 1 2 1, or to one spin-1 nucleus to give a multiplet with three peaks with relative intensity ratios of 1 1 1. 

A significant problem arises once we make the leap to the second dimension. For a basic 2-D H COSY spectrum, we might wish to
