NMR Week 6

We met Erwin Hahn! Who honourarily (?) graduated on Monday with the other physicists :) Go here to see him and the rest of us!

Work-wise I did more simulations using Spin Evolution, but this time using different pulse sequences. Amy did the equivalent using Simpson so we can compare.

Experimentally we had planned to run quite a few samples on the 600 MHz spectrometer but we had difficulty with various things so we didn’t get as much done as expected (research is seemingly a very slow process at times!).

On Thursday I did a 4-spin simulation using Spin Evolution. I chose atoms in the penicillin molecule to check that interatomic distances were represented on the spectum as expected. I also looked at the effect of changing the spinning speed and number of propagations.

Friday we ran a 2D experiment on sample B04. We got a lot of noise so left it running over the weekend.
