UW CHEMISTRY NMR

The 13C channel tuning problem has been fixed.   I would like to emphasize the following:  ” please be gentle with the tuning and matching knobs; do not use excessive force and try to turn them beyond their stop position, ever ! ”

Along with this, we have also made sure that the 1H channel tuning is more smooth. The probe is shimmed up so that you should use the standard shim set : stdtbi before starting your own Topshim routine.

Please keep us posted of any abnormalities.  Use the log book to record your observations.
