Definition: matching space group and unit-cell dimensions, with corresponding atom types/positions except permitted atomic replacement or addition. The definition distinguishes this crystallographic relation from equality of composition alone.

Core CIF dictionary item _atom_site_occupancy, Definition: fraction of the atom type present at a site; summed occupancies of types sharing a site should not significantly exceed1 unless a dummy site is modeled.

Entry15367, DOI10.1351/goldbook.15367. Definition: straight line connecting compositions of independent coexisting equilibrium phases on a phase diagram. Original source: Glossary of terms related to solubility, IUPAC Recommendations2008, Pure and Applied Chemistry80,233, p.270; synonyms connodal/conodal.

International Union of Crystallography dictionary item _phasing_MIR_der_site.occupancy: fraction of the atom type present at a heavy-atom site in a specified derivative.

Nature185,422–427(1960), published13February1960. First author J. C. Kendrew. Page422, opening paragraph: earlier myoglobin phasing compared unsubstituted crystals with several derivatives containing mercury or gold at single sites, determining phases for spacings greater than6Å. The report then presents the2Å analysis.

IUPAC Green Book, third edition(2007), second printing(2012). Official title page identifies IUPAC and publication editors. Section2.11, printed pp.57,59: relative activity $a=\exp [(\mu -{\mu }^{\circ })/(RT)]$ and Raoult-reference activity coefficient; section2.11.1(iv), printed pp.61–62: distinct pure-phase and solute standard states. Activities and their standard chemical potentials must use matching conventions. No individual editor identity inferred from abbreviated bylines.

Section2.11, printed p.58: reaction quotient, standard reaction Gibbs energy and standard equilibrium constant; note18 states that the equilibrium constant is dimensionless and depends on the specified standard state.

T06410, DOI10.1351/goldbook.T06410; two definitions distinguish reconstructed sum after mass analysis from all same-sign ion currents before mass analysis. Original recommendation PAC63,1541(1991), p.1554. Related total ion current profile entry goldbook.iupac.org/terms/view/12600 defines the time-dependent plot.

Abstract: distinguishing matrix effects and recovery, and comparison of ion-spray versus heated-nebulizer interfaces for the investigated compound under otherwise matched preparation/chromatography.

Primary university alumni newsletter, issue1/2010, PDFp1: LAMMA-1000 article and caption identify Michael Karas at left in the development-era laboratory photograph and a separate portrait at right. Used only as a primary portrait/apparatus reference; the PDF screenshot reader returned a cache miss.

Primary CCP4 documentation, SIR—Single Isomorphous Replacement and MIR—Multiple Isomorphous Replacement. Vector-circle construction gives two possible protein phases from one derivative; a consistently positioned additional derivative can add a resolving constraint. The article supplies its own amplitudes for an illustrative calculation.

Analytical Chemistry 57, 2935–2939 (1985). Original first-page byline Michael Karas, Doris Bachmann and Franz Hillenkamp. Page 2937, Figure5 and “Matrix-Assisted Laser Desorption”: alanine/tryptophan mixture at 266nm, alanine ion formation at about one tenth of the irradiance required for alanine alone. The paper discusses competing mechanistic interpretations rather than establishing one universal ionization pathway.

Analytical and Bioanalytical Chemistry 401(1), 167–181 (2011), DOI 10.1007/s00216-011-4929-z. Byline: Sören-Oliver Deininger, Dale S. Cornett, Rainer Paape, Michael Becker, Charles Pineau, Sandra Rauser, Axel Walch and Eryk Wolski. Introduction, “A pledge for normalization”, and Figures 1–4 compare spectrum-wide scaling and artifacts from locally abundant signals.

Primary curated polymer record CHEBI:53325: definition, functional parent, structural drawing/SMILES and cellulose-nitrate synonym. Structure shows O-linked nitrate esters on a cellulose-derived backbone. The article repeat-unit calculation is independent atom bookkeeping, neglecting finite-chain end groups; the record’s displayed capped-chain formula is not treated as a universal formula for every substitution level.
