##### Simulations / 1H-31P Coupling
« on: November 18, 2013, 03:13:58 AM »
Is there an example for 1H simulation considering the coupling from P-31?

Thanks.

##### General Discussion / Plotting NMR spectrum in Mathematica
« on: January 13, 2013, 03:51:48 AM »
I am trying to plot NMR spectrum (with a list of data points) in Mathematica, but it gave me reverse ordered spectrum where 0 ppm is shown on the left, and higher value like 10 ppm is on the right side.

How to plot the spectrum with descending x-axis, like having 10 ppm on the left and 0 ppm on the right side?

Thanks.

Those video lectures on simulation design and coding are very helpful. Hope to see a set of video lectures on Spinach.

##### Spinach feature requests / Function explanation and help
« on: September 09, 2012, 04:05:39 AM »
I found it is very easy to find the explanation for any function in SpinDynamica, like in Mathematica, just by typing "?***" in the .nb file.

I hope Spinach can also offer such easy way. It is difficult to locate and find the explanation for functions in the package.

Thanks.

##### General Discussion / how to convert density matrix into density operator?
« on: September 09, 2012, 04:01:05 AM »
If I have the density matrix for para-Hydrogen as 1/2 {{0,0,0,0},....}, how can I convert it into Bra and Ket form? Thanks.

##### Simulations / density matrix simulation for parahydrogen induced polarization (PHIP)
« on: August 05, 2012, 09:18:12 PM »
I wonder if there is an example for simulating PHIP?

I just downloaded SpinDynamica and am trying to get started, but no idea how.

Thanks.
