| Experiment Setup |
-
- Use getprosol or prosol button to read in proper pulse parameters
- Set cnst2 = 1JCH coupling constant: default cnst2 = 145 Hz
|
| Processing Notes |
-
- Fourier transform with the command xfb
- Manually phase F2 and F1 dimensions
- Use commands abs2 and abs1 for baseline correction
- For improved resolution, can try applying linear prediction in the F1 dimension. In the ProcPars tab set the following parameters:
- ME_mod = LPfr
- NCOEF = set to 3 times the number of cross peaks in your spectrum.
- LPBIN = 2*TD(in F1)
- Fourier transform the spectrum again with xfb
