Rdf calculation

WebRDF = ADF * Q† (9a) Note the factor Q† should reflect the corrected RDF value. Of course the original definitions of RDF (and thus equation 9a) did not account for the ‘[1 / (1 – .005161 * RE)]’ correction term. It was noted that Balling first pro-posed calculating the ratio of RDF/ADF20 and it is termed ‘Balling’s shorter formula’. WebThe formal definition of the RDF is g i ( r) = n i ( r) 4 π r 2 δ r ρ where n i ( r) is the number of particles between distances r and δ r , and ρ = N V is the number density. Dividing by ρ ensures that the RDF is centred around 1 when the density of particles observed at some distance does not deviate from the bulk density.
