Hi Karin,

Hello,
I'm trying to do a quick first shell fit with Artemis for my EXAFS measurement of 0.1 M auqeous solution of RbCl. I'm especially interested in the first hydration shell of the Rb ion. So I made an atoms input file with Rb and O in Rock salt structure. But how do I consider the Cl ion in the quick first shell fit? I don't think I can overlook the scattering on the Cl ions.
Best regards, Karin

You'll need to make a scattering path for Rb-Cl, say starting with the RbCl crystal structure. Then, you'll want to fit the first shell with a mixture of Rb-O and Rb-Cl, possibly allowing the relative amount of Rb-O to vary in the fit. There are lots of examples of doing that, but the first step is to make the Rb-O and Rb-Cl scattering paths. --Matt
