Some notes on finding the NMR resonances.

FIRST: make sure you do the 'configuration/connect', otherwise
the program isn't talking to the NMR setup. It should take a
few seconds and then show 'connected' to 'Serial #102'. 

It can be hard! When I demonstrated the NMR setup in lecture, it
looked like there wasn't a sample. But there was, it was just
out of view.

So, some hints on finding the NMR resonances: set the "gain"
resonably high, 50 or so, and move it higher if it looks like
there's a small "blip" that could be the resonance.

Use the magnetic field scan (B scan) and set it to a fairly large
value: it's set by default to 5 G.s, and I had to use 50 G.s, and
then suddenly the resonance showed up on the right side of the
display.

Once you find a resonance in the scan, you can adjust the B0 value
(the 'central' magnetic field: the B-scan goes from below B0 to
above B0) to move the resonance to the center of the display, THEN
decrease the B-scan size, and increase the 'scan time' to get better
data. 

If your resonance doesn't look like the nice 'blip' shown in the
NMR_setup.PNG screen-capture, try adjusting the 'phase'

Good luck!
