Comparing the database values also clarifies that diamond's actual (111) interplanar spacing is 2.06 A (with conventional cell edge a = 3.567 A) whereas sphalerite's d(111) is 3.12 A, while both rigorously contain 8 atoms per unit cube. https://w3id.org/delphi/resource/assessment/bragg1915-04--gemini http://purl.org/dc/terms/subject https://w3id.org/delphi/resource/concept/dataset-resolvability-0.2.0 https://w3id.org/delphi/resource/assessment/bragg1915-04--gemini http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/LLMClaimAssessment https://w3id.org/delphi/resource/assessment/bragg1915-04--gemini http://www.w3.org/2000/01/rdf-schema#comment Proposed test with existing data: From crystal structure determinations of diamond (C, Fd-3m) and zincblende/sphalerite (ZnS, F-43m), evaluate the invariant d_111 * (rho / m_bar)^(1/3) (where m_bar is the mean mass per atom or formula unit) and count the total number of atoms per conventional cubic unit cell.
