Diffraction Diagram

Fig.1 Diffraction pattern from 2-fold E. coli M41 polysaccharide. Two chains pass through the orthorhombic unit cell with dimensions a = 2.03 nm, b = 1.178 nm, and c (fiber axis) = 3.04 nm. The meridional direction is vertical and the sample was tilted from a direction normal to the beam by 9°.
