An example of the former is dicyclopentadiene, which is a dimer of ]. It can refer to halide chemistry, involving halogen bonding. Its more common usage refers to dimers as certain types of ]: ], for example, is a dimer of a ] molecule and a ] molecule.

	A '''physical dimer''' is a term that designates the case where intermolecular interaction brings two identical molecules closer together than other molecules. There are no ]s between the physical dimer molecules. ] is such a case where ]s provide the interaction. The ] is another dimer of interest, used for modeling hydrogen bonding in water.

	==Biochemistry==
	In ] and ], dimers of ]s like ]s and ]s are often observed. The dimerization of identical subunits is called '''homodimerization''', the dimerization of different subunits or unrelated ]s is called '''heterodimerization'''. Most dimers in biochemistry are not connected by ]s with the exception of ]s.
	An example of this would be the enzyme ], which is made of two different ] chains.

dimer (n) - a person with balls the size of a dime. most character traits of a dimer are bitchy, dramatic, NOT normal, fucking stupid, WEIRD, wigger, and meanie. dimers are often spotted talking to the television, computer, birds, or girls with gaps in their teeth. also see porcupine balls.
