For some reason the shape tool has some sort of glitch that I can't calculate a power level for a wurst 10 ms pulse 180 rotation for a a 522 max gamma ~ for over 3000 Hz, with an option "Analyze adiabatic shape".
It insists it is not an adiabatic shape.
So I tried opening the same file shape tool in XWIN-NMR shape tool and the same problem occured but this time it gave me the Hz covered in maximum gamma when I included the degrees of rotation as well as the time for the pulse. it covers a 3ppm bandwidth etc.
I think I've done this many years ago but can't find my notes on it. Is there a way to calculate this?Thanks.R

[Question from NMRWiki Q&A forum] How do you build an NMR power amplifier?
How do you build an NMR power amplifier?
And how to you match it to the NMR coil?
Basically I'm looking to perform NMR experiments with frequencies in the 500KHZ region. I already have an arbitrary function generator that I can program with the required pulses at that frequency, now I need to amplifier the signal, and deliver the current to a coil.
How do build an amplifier that can drive a lot of current into a coil at that frequency? Do I resonate the coil with a capacitor, and if so, how do I ensure the resulting circuit won't ring, and ruin the pulse sequences?

[NMR analysis blog] Basics on Arrayed-NMR Data Analysis (Part III): Extracting and calculating useful NMR
Basics on Arrayed-NMR Data Analysis (Part III): Extracting and calculating useful NMR related molecular information
After the basic introductory posts on arrayed NMR experiments, it’s now time to get some action and see how to extract relevant information from these experiments and calculate useful NMR related parameters such as diffusion, relaxation times, kinetics constants, etc.
Actually, in this post I will cover the first case, that is, the analysis of PFG experiments to calculate diffusion coefficients. The reason for this is twofold: (1) I have a nice PFG data set whilst the...
