IU NMR Facility

A problem of the pulse gradient driver on I500 has been fixed. All gradient versions of 1D and 2D experiments as well as diffusion experiments are working now.

Mestrenova 10.0.2 and its two plugins qNMR 1.2.1 and RM (Reaction Monitoring) 1.1.0 are now available for download from the ITG web site. We recommend that every user upgrade to the latest version of Mnova and its plugins. Go to the ITG web site and follow the instructions there.

To see what’s new in the new version, go to http://mestrelab.com/software/mnova/whats-new. You may also want to learn about qNMR plugin at http://mestrelab.com/software/ mnova/qnmr and RM plugin at http://mestrelab.com/software/mnova/rm.

We recently purchased a new license with 150 seats for Mestrenova software. This would provide enough license seats for all NMR users at all times. We recommend all users upgrade to the latest version (10.0.2) which will be available for download from the ITG web site soon.

A Nalorac 4-Nucleus probe has been installed on VXR400 for routine operation, replacing the Broadband probe. Like I400, users can now acquire 1H, 13C, 19F, and 31P spectra on the VXR400 without need of probe switch/tuning.

Please note that the old parameters you saved previously with the Broadband probe should NOT be used for the newly installed 4-Neclues probe (i.e. do not open one of your old FID files and click “acquire” or type “ga” to acquire new data). You should go through the standard experiment set-up procedures: click on “Experiments” in the menu bar then select a nucleus or an experiment. This would ensure to load appropriate parameters that were calibrated for the currently installed probe.

We will be doing advanced NMR training on August 18th, Tuesday from 10am-noon. This will be a single 2-hour session focused on 2D NMR experiments (see the previous post) and it’s free of charge. We’ll be at an instrument so please email Frank for reservation. Also let him know if there are other days or times that would work better for you, as well as questions or specific requests.

A hardware problem which caused the spectrometer frequently to become “inactive” in the past two weeks has been fixed.

I600 is open to users again. A problem which sometimes caused long term experiments to stop early giving rise to incomplete data set has been fixed. If you have never used this spectrometer, please find the spectrometer information here.

The macro command emaildata has been modified and now works on I600.

The macro command iuexit has been modified and now works on I600. You can type iuexit or click Exit VnmrJ and Logout on VNMRJ GUI to exit VNMRJ and logout your account in one step.

I’m considering having one more “advanced NMR training” session next week. It you’re interested, email Frank with your time preference (please choose as many as possible from the following time slots: Tuesday (1/20) – Friday (1/23), 10am-noon, 2-4pm).
