Solvation Sphere of I^- and Br^- in Water
Antalek, Matthew D. .
The solvation sphere of halides in water has been investigated using a combination of extended x-ray absorption fine structure (EXAFS) and x-ray absorption near-edge structure (XANES) analysis techniques. The results have indicated that I^- and Br^- both have an asymmetric, 8 water molecule primary solvation spheres. These spheres are identical, with the Br^- sphere about .3 A smaller than the I^- sphere. This study utilized near-edge analysis to supplement EXAFS analysis which suffers from sign...

The solvation sphere of halides in water has been investigated using a combination of extended x-ray absorption fine structure (EXAFS) and x-ray absorption near-edge structure (XANES) analysis techniques. The results have indicated that I^- and Br^- both have an asymmetric, 8 water molecule primary solvation spheres. These spheres are identical, with the Br^- sphere about .3 A smaller than the I^- sphere. This study utilized near-edge analysis to supplement EXAFS analysis which suffers from signal dampening/broadening due to thermal noise. Show Partial Abstract
