Since most of the synthetic chemists are gallivanting around Denver for the ACS meeting, I decided to put the TXI probe in Paris. This probe gets much better sensitivity for 1H detected experiments (like the HSQC) at the expense of less sensitivity for 13C (or other heteronuclei) detected experiments. So Friday afternoon I swapped the probes. I've noticed that I always have a trickier time getting Paris shimmed back into spec than any other instrument. Fortunately, I took advantage of some computer aided shimming and was acquiring data by Saturday night. So far it looks good. I'll probably leave this probe in the instrument for a couple of weeks so that I can collect some spectra on a sample in 90% H2O/10% D2O for a client. Turns out I get better water suppression with the TXI probe than the BBO probe.
With the start of the semester, the ACS meeting and a holiday next Monday, this week seemed like a perfect time to play these games.

EPR Lab processing station
EPR Users -
I wanted to take a moment and inform everyone about our new EPR processing station in Malott 1002. The computer is adjacent to the EPR workstation (which controls the spectrometer). Both computers share a keyboard, mouse and monitor via a KVM switch, which is just a little black button next to the keyboard. To switch back and forth between the computers, just push the button!
Presently there is generic user "EPR User". If you choose this user from the list, the account should open automatically. I have installed EasySpin (http://www.easyspin.org/), a popular, robust and powerful spectral simulation tool. EasySpin requires MATLAB. Currently we have a 1 month (now 27 day) trial of MATLAB installed.
I would request that everyone who has recorded data on the EPR, please try out the processing station as much as possible over the next 27 days. Before we purchase a license for MATLAB, we would like to assess a) if EasySpin will suit the needs of the KU EPR community; b) if the current computer is powerful enough for our purposes.
I'm working on some documentation to help get started with EasySpin, so stay tuned.
