| 词条 | Homometric structures |
| 释义 |
In chemistry and crystallography, structures of identical atoms that are characterized by the same set of interatomic distances are defined as homometric structures.[1] Homometric crystal structures produce identical diffraction patterns; therefore, they cannot be distinguished by a diffraction experiment. Recently, a Monte Carlo algorithm was proposed to calculate the number of homometric structures corresponding to any given set of interatomic distances.[2] See also
