A new method for 14N NMR spectroscopy

Luke O'Dell and Rob Schurko have been investigating a new method of acquiring 14N NMR spectra in the solid state, and the work is described in J. Am. Chem. Soc. 2009, 131, 6658–6659, DOI: 10.1021/ja901278q. 14N NMR spectrosocpy is very difficult experiment to conduct on most solid-state samples, because 14N is a quadupolar nucleus, and most cases the 14N NMR patterns are hundreds of kHz to several MHz in breadth. The new method involves the use of special pulses called WURST pulses, which are capable of sweeping wide frequency ranges, along with the collection of long echo trains to further enhance the signal to noise. They have also reported that the swept pulses actually enhance the overall S/N of the spectrum, and have dubbed the method as "DEISM" (Direct Enhancement of Integer Spin Magnetization).

Mango Party - May 28, 2009

Dr. Pandey's annual mango party will take place on Thursday, May 28 at 3 p.m. on the front steps of Essex Hall. Make sure you are there!!

NMR workshop, May 20 and 21

NMR Workshop Announcement:
On May 20 and 21 from 9:00 am until 12:00 p.m., the Department of Chemistry and Biochemistry NMR Facility at the University of Windsor is offering a workshop entitled "An Introduction to Practical Aspects of NMR Data Acquisition and Processing".

This introductory workshop, which runs over two mornings, is geared toward incoming summer students and/or graduate students with little or no NMR experience, but who are expected to make use of the NMR spectrometers as part of their summer project. The workshop is meant as supplement to the "one on one" training that new students receive and will allow an opportunity to go into greater depth on many topics.

There will be mixture of lecture sessions and hands on learning opportunities for the participants. In addition to myself, Rob Schurko, Aaron Rossini and Hayam Hamaed will helping with the sessions. The topics covered include:

  • Preparation of NMR Samples
  • Set up of 1D 1H and 13C NMR Experiments
  • Processing and Presentation of NMR Data

Click here to see the schedule and register for the workshop.

The workshop is free of charge to members of the Dept. of Chemistry and Biochemistry; however, enrollment is limited, so please register soon!
