The McGill TopSpin addons have been updated.  These are plot layouts and automation routines which simplify and improve processing.  Instructions are available at http://nmr.chem.mcgill.ca/en/nmr/manuals.  Get the addons themselves by emailing Robin.

There will be a power outage in the NMR rooms on Friday, Sept. 21 from 9 to 11 AM.  The instruments will be turned off beginning at 8 AM.

As far as I know, only the NMR rooms are affected.

We’ve got the Mnova licenses for 2018-2019.  The old ones will still work, but if Mestrelab introduces a new version of software, you’ll need the new ones.  Ask Robin for the new licenses if you don’t have them.

NEVER remove samples from the autosamplers if they are in the queue (pink in the diagram).  Be very careful about the number of the position you remove!  If you do remove a sample that is yellow or green in the diagram, note down the number and put it in the same spot in the rack.  If there is no space, move one of the samples already in the rack to a position in the front where there is no number.

NEVER allow anyone who has not been trained to be in the NMR room on their own.  This is for safety and because I want to be sure that I know what is being told to new users.  Training is free and usually scheduled within a week of when it is requested.  Training can be requested at http://nmr.chem.mcgill.ca/training – please direct new members to this site.

The Varian 500 is currently set up to do 1H and 31P only.  Do NOT try to do 13C.  Read here for instructions on tuning.  Do NOT tune 31P.  More information about experiments is available here.

All rules are listed here.  Instrument signup rules are on the instruments page.

Contact me (email: robin.stein@mcgill.ca, phone 514 398-6219 – this goes to my cell phone) if there are any problems or if you have questions.

The usual probe that we use on the Varian 500 is not working and so we currently have an inverse probe tuned to 1H and 31P.  You can run experiments using 1H and 31P on it.  Do not tune the 31P channel, only the 1H (blue curve in trtune).  Notes about using the spectrometer are available here and notes on tuning are here.

The main units in rooms 34, 35, and 37 will be removed and replaced in September. During this time, there will be no EPR. Solid-state NMR access is currently unclear. Liquid-state NMR access will probably be reduced because overheating will be likely.
