The NMR Facility is open for "normal" operations. Read the guidelines below.
The MR Facility is fully available under normal operating procedures.
1. All new users of the facility must go through training – do not use any portion of the facility until you have completed the appropriate training to use that equipment. New users start by signing up for NMR training and follow the instructions on the canvas site. The in-person portion of the training is available every Friday at 11am; sign up for it on the google sheet. This training provides access only to one 400 (Artemis) and one 500 (Callisto) MHz NMR spectrometers in the facility.
2. All training is provided by NMR staff. Assistance and learning by groupmates is helpful, but may not replace approved training.
3. Artemis (av400) and Callisto (DCH500) are available under total automation using IconNMR. See this video to remind yourself how to use IconNMR, and for guidance and rules for use of the spectrometers. See below for comments about sample removal from the facility.
4. All other instruments are available via our calendaring (FACES) system at nmr.chem.wisc.edu. Please be collegial with scheduling your time. All of these instruments require additional training for use. If you have not been trained and have a justifiable need, contact NMR staff.
— Phoebe (av600) and Nyx (operando 500) are liquids use only.
— Eos is used extensively for Chem636, Chem344, Chem346 and other courses. That use will be on the calendar. Researchers can schedule in any time not already taken by the lab classes. Nyx is recommended for now for VT experiments.
— Persephone (ss500) will be used primarily for solid-state NMR studies. Contact Cathy (clewett@wisc.edu) for details prior to scheduling time.
— SQUID, Mossbauer, and EPR are available via calendaring.
If you have questions or concerns, contact NMR staff using nmrstaff@chem.wisc.edu. Please also include your advisor’s name in the email
Information about COVID-19 compiled by the department can be found here.
NMR Facility hours match the Chemistry Building hours: users should not enter the building or Facility outside of these hours.
*********** Policy for Sample Removal *********************************************
It is the responsibility of every user to remove their samples promptly from the MR Facility. Chemical safety is a priority, and the facility cannot provide storage of samples. The introductory training video for artemis and callisto provides more detailed information. Users must know how to interact with the 1-day, 2-day, and overflow racks that are used to assist with sample removal.
In brief, samples should be removed from the facility within 24 hr of their finishing on the spectrometer. If they are still present the following weekday morning, an email will be sent reminding users to remove the samples that day. Repeated violations in not having samples removed from the facility within 48 hr may result in loss of instrument access and/or fines.
*********** Other news *********************************************
The new 500 MHz spectrometer, Nyx, is available to users that have appropriate training. New capabilities for operando operation are available, and a liquid-N2-cooled (Prodigy) probe is installed that can detect most NMR-active nucleus. It will operate over a VT range of -35 to +70C. The functionality is similar, but with better sensitivity, to what Eos and Persephone (when in liquids mode) have. Chem 636 or equivalent training is a prerequisite to gaining access to Nyx.
Phoebe (600) is available to all users. If you want to use the instrument, email nmrstaff@chem.wisc.edu to setup training. Be prepared to answer why the 600 will be necessary for your research.
The full MR Facility has resumed “normal” accounting practices for applying charges. Be aware that fees are not based on calendar requests, nor are they based on IconNMR use (except for Artemis and Callisto). Under calendared use, charges are based on the time logged into the spectrometer (independent of whether an experiment is running or not). That has worked well in the past, and is an accurate and efficient method for doing the accounting. It is the user’s responsibility to sign-up and use just the time needed under calendared use. Log out when done. If the user assumes someone else will logout for them and that does not happen, the full amount of time the user is logged in will be charged. Do not signup for a set of short experiments unless someone will stick around to log out when the experiments are done.

Welcome to the Chemistry NMR Facility
The Chemistry Department’s Nuclear Magnetic Resonance Facility supports a broad range of chemical research. Large numbers of compounds can be run using walk-up access and automation. Sample temperatures can be used from -150 to +150oC. Experiments can be performed on all magnetically active nuclei (excluding radioactive). Reaction monitoring, kinetics, chemical exchange, diffusion, ligand exchange, and quantitative measurements are regularly run in the Facility. Solid-state NMR (ssNMR) is a new addition to the facility, enabling the study of samples in either the solid-state, but also samples that have very high molecular weight in solution or in gel form. A dedicated website is available for ssNMR here.
The Facility has seven NMR spectrometers located in the Paul Bender Chemistry Instrument Center (PBCIC). We are still primarily a student-run operation, but service work is available to corporate users. Access is obtained via training and coursework, provided by the facility staff. Detailed Users Guides are available to assist in the use of all UWChemMRF equipment.
