Figure 4.11. Routing for a Double Resonance Experiment, Changed for Proton
Observation
In the figure above channel F2 need not be used.
The settings for F1 and F2 are interchanged. Change rg to 8-16 and d1 to 4 sec.
Set pl1w to 50W, or to 10 dB (high power proton transmitter), 7 dB (500W proton
transmitter), 5dB (300W proton transmitter) or -4 (100W transmitter), if the green
dot does not appear in the
1
H channel in edasp. Connect the probe proton chan-
nel to the proton preamp. A proton band pass filter must be inserted between pre-
amp and probe. Tune the proton channel of the probe using the command wobb
high. This means that the highest frequency is tuned first. Stop and type wobb
again. Then adjust the tuning of the X channel to
13
C. Alternatively, you can
switch to the lower frequency channel within wobb high by clicking on the fre
-
quency table symbol in the wobb display or by pressing the second touch button
on the preamp cover module twice. Then acquire ns =2 scans on the protons of
adamantane.
