3.6 REFERENCE SETTING
In the solid-state NMR, the reference cannot be corrected by using the lock signal as in
the solution NMR. Therefore, the reference is set up using the spectrum of an exter-
nal-reference sample. There are two methods for setting the reference: setting in the Delta
and setting using the Z0 shim.
3.6.1 External Reference Setting
1.
Prepare the spectrum with the external-reference substance, and carry out
the reference setting.
Refer to the user’s manual “Data processing” for details for setting the refer-
ence.
