Solvent suppression using excitation sculpting
The pulse programs using this all have names such as: “I_NAME_+suppression” and are easily read in from iconnmr.
The parameter to adjust is called “ o1 ” (value in hertz) or “ o1p ” (value in ppm)
NB: this is different for different solvents and it may vary if you have additional solvent components. If in doubt, first run a proton spectrum and determine the center of the solvent peak using the cursor.
On the 500 MHz spectrometer (NEO500) the following “o1” values can be used:
- D 2 O = 2352.02
- DMSO in water = 1965.61
- DMSO = 1250
- Methanol = 970
- CDCl 3 = 3630
- CD 3 CN = 970
