TI  - Quantitative analysis of x-ray absorption near edge structure data by a full 
      multiple scattering procedure: the Fe-CO geometry in photolyzed 
      carbonmonoxy-myoglobin single crystal.

AB  - We report the first quantitative analysis of the Fe K-edge polarized x-ray 
      absorption near edge structure of the iron protein carbonmonoxy-myoglobin (MbCO) 
      single crystal and of its cryogenic photoproduct Mb(*)CO. The CO-Fe-heme local 
      structure has been determined using a novel fitting procedure based on the full 
      multiple scattering approach. The extracted local structure of Mb(*)CO includes a 
      Fe-CO distance of (3.08+/-0.07) A, with a tilting angle between the heme normal 
      and the Fe-C vector of (37+/-7) degrees, and a bending angle between the Fe-C 
      vector and the C-O bond of (31+/-5) degrees.
