The model can be obtained by clicking on the small "thumbnail" picture of the DNS oligomer in the top right corner. The spectrum is as you see it. The interpretation is provided by clicking on individual cross-peaks.
There are two types of nOe cross-peak. Those arising between close approach of the anomeric and aromatic protons of the SAME base, and those arising out of proximity between an anomeric proton and aromatic proton of DIFFERENT bases. To take full advantage of this analysis, you will need to install the RasMol program on a Unix Workstation. Click first on the image of the DNA loop to activate the Rasmol viewer. Click then on coloured cross-peaks in the 2D NOESY spectrum to trace out the NOE connectivity.
