DOSY Data Analysis Using XWINNMR:
Fitting Diffusion Coefficients
1. After you have processed (xf2) and phase corrected the data you will observe a
DOSY spectrum similar to the one shown below.
2. Under the submenu Analysis choose Relaxation [ T1/T2 ].
3. Type rspc in the command line or under Process choose Read SMX slice for
peak selection. You will now observe the first 1D spectrum from the 2D dataset.
4. In the utilities submenu define the peaks for which you wish to fit a diffusion
curve. Select defpoints and using the middle mouse button define the peaks. Save the
peak file and return to the Relaxation [ T1/T2 ] menu from the Analysis submenu.
