2D NMR Training, October, 2022
We will be doing 2D NMR training next week at the following times:
October 12, Wednesday, 11:00 am – 1:00 pm;
October 12, Wednesday, 3 pm – 5 pm;
October 13, Thursday, 11:00 am – 1:00 pm;
October 13, Thursday, 3:00 pm – 5:00 pm;
October 14, Friday, 11:00 am – 1:00 pm;
October 14, Friday, 3:00 pm – 5:00 pm.
These will be single two-hour sessions. I will discuss the basic concepts of 2D NMR followed by the setup, acquisition, processing, and plotting of the common 2D NMR 1H-1H and 1H-13C experiments including COSY, TOCSY, NOESY/ROESY, HMQC/HSQC, and HMBC/CIGAR. The number of attendees in each session will be limited to four. Please sign up using the online sign-up sheet if you plan to attend.
The maximum occupancy of each training session is four students. The sign-up form will be closed on Tuesday (10/11) at 5:00 pm. So, if you are interested, please, sign-up for the training ASAP.

Solvent Selection on B500
Unlike VnmrJ software on Varian spectrometers which contains only deuterated solvents in the solvent list, IconNMR software on the B500 contains both deuterated and non-deuterated solvents in the solvent list. All non-deuteared solvents are marked with “non-deuterated” following the solvent names, therefore are easy to distinguish. Here is a example:
“CD3CN acetonitrile-d3” — this is deuterated
“CH3CN acetonitrile, non-deutareated” — this is non-deuterated
For a sample in deuterated solvent (almost all of the samples for NMR measurement use deuterated solvents) , you must select a matched deuterated solvent (CD3CN in this example). Selecting a non-deuterated solvent (CH3CN in this example) would result in failures of locking and/or shimming and consequently failure of the experiment. Do not make this mistake.
Update 2022/9/21: All non-deuterated solvents were removed from the solvent list to avoid possible confusion.
