Investigation of the local structure of the high‐temperature liquid and solid phases in the 300‐725 K range of AgBr has been performed using the x‐ray absorption spectroscopy (XAS). Structural results are compared with existing diffraction studies and computer simulations demonstrating the reliability of the XAS technique in determining the short‐range structure. Present results on solid AgBr are in agreement with known thermal expansion data. The short‐range g ( r ) of liquid AgBr is reconstructed showing the unique insight provided by the XAS technique in measuring short‐range atom‐atom correlations in liquids.
