Shim file

Read a shim file suitable for the NMR solvent and solvent volume ( 40 mm) being used. [Pg.823]

If it hasn t been done already, prepare the NMR sample, set the temperature, and read a shim file as described (see Basic Protocol, steps 1 to 4). [Pg.825]

If shims are really bad, you may be able to recall a recent shim file from the disk. Ideally, a spectrometer should be shimmed regularly (daily or weekly) by an expert, and these current shims should be saved. Rather than waste a lot of time trying to get home from someone else s / /-dimensional wanderings away from the optimum, you can just read the latest shim file and start from there. Of course, you will still need to adjust Z1 and Z2 because these change a great deal based on the sample volume, position, and polarity of the solvent. [Pg.87]
