Crossword clues for dimer
The Collaborative International Dictionary
oligomer \o*lig"o*mer\, n. (Chem.) A molecule composed of a small number of linked monomer units; a short polymer; -- compounds called oligomers have less than one hundred monomer units and usually less than thirty. Oligomers of increasing length are called dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, decamer, etc. In colloquial laboratory jargon, they may also be referred to as nine-mer, ten-mer, eleven-mer, twelve-mer, etc., especially for oligomers of greater than eight units.
Wiktionary
n. (context chemistry English) A molecule consisting of two identical halves, formed by joining two identical molecules, sometimes with a single atom acting as a bridge.
WordNet
n. a compound whose molecules are composed of two identical monomers

A dimer (di-, "two" + -mer, "parts") is an oligomer consisting of two structurally similar monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A-A) and heterodimer when they are not (e.g. A-B). The reverse of dimerisation is often called dissociation.
Dimer may refer to:
-
Dimer (chemistry), a chemical structure formed from two similar sub-units

- Dimer model, an item in statistical mechanics
- Julius Dimer (1871–1945), a German chess master
