cuso4 pentahydrate low field
Posted: Fri May 25, 2018 11:54 pm
Hello,
How do I set up for this material? I'm trying to simulate a pulse into CuSO4 dissolved in water at a specific field and frequency. I'm looking for a time domain simulation of the response to a shaped waveform. I am not particularly well versed in chemistry so I don't know if there is an offset associated with the rightmost peak at g=2.09 due to the hyperfine interaction. My impression is that
the Oxygen and Sulfur have no nuclear field so it would only be the Cu. Naively I would imagine that the frequency of the rightmost peak in the CW spectrum would be approximately:
2.09/2 * 2.8 MHz times the field in Gauss.
But is there a shift in frequency due to the Cu nucleus? As you can see I don't quite get it. I would expect at 1000 G the frequency of that peak would be
exactly 2926 MHz. Is it different? For TEMPO, I have read that the Nitrogen nucleus has a 16 Gauss nuclear field. Where do you look that number up for Cu? Does that number depend on the
polarizing field. I hope you see what I am baffled about.
thanks
