Repeat steps 1 to 5 above. Although the echo maximum may change position,
symmetry of the horns should be the same. The edges of the spectrum will alter and
become sharper. This flag (i.e.,
compul
) changes the
π
/2
pulses from single to
composite and so checks the 90° phase shifting speed of the spectrometer. Refer to
Figure 12 and Figure 13 .
9. Repeat steps 1 to 4 above for sample 00-969104-01, the sodium solid standard
sample; tune the probe to the sodium frequency. Recall the standard test parameter
by entering
rt('/vnmr/tests/Na23wl')
. The sodium solid standard FID
appears similar to the example in Figure 14 .
