Bond-orientational order
WebThe orientational order, recorded for 21 different electrolytes, starts to change at ionic strengths <10 μM. This seemingly long-range and universal effect is independent of the chemical structure, polarizability, and size of the ions. WebFeb 10, 2024 · Bond order parameters, q l and their averaged versions, q ¯ l are widely used to identify atoms belong to different crystal structures. In this example, we will consider bcc, fcc, and hcp, and calculate the q 4 and q 6 parameters and their averaged versions which are widely used in literature. More details can be found here. [1]:
