When X-rays interact with a crystal lattice, they scatter in specific directions, creating a diffraction pattern that encodes information about the atomic arrangement within the crystal.<\/p>\n<p>Key principles include:<\/p>\n<ul>\n<li><strong>Bragg&#8217;s Law<\/strong>: This law, expressed as <span>n\u03bb = 2d sin\u03b8<\/span>, relates the wavelength of the X-rays (\u03bb), the spacing between atomic planes (d), and the angle of diffraction (\u03b8). Understanding this equation is vital for interpreting diffraction patterns.<\/li>\n<li><strong>Space Groups<\/strong>: These describe the symmetry operations that define the arrangement of atoms in a crystal. Mastering space groups helps in determining the crystal&#8217;s structural properties.<\/li>\n<li><strong>Diffraction Patterns<\/strong>: These patterns are analyzed to reconstruct the three-dimensional structure of the molecule.
