Editing Racemization (section)

== Physical properties ==
In the solid state, racemic mixtures may have different physical properties from either of the pure enantiomers because of the differential intermolecular interactions (see Biological Significance section).  The change from a pure enantiomer to a racemate can change its density, melting point, solubility, heat of fusion, refractive index, and its various spectra.  [[Crystallization]] of a racemate can result in separate (+) and (−) forms, or a single racemic compound. However, in liquid and gaseous states, racemic mixtures will behave with physical properties that are identical, or near identical, to their pure [[enantiomer]]s.<ref name="Mitchell_1988">{{cite journal | vauthors = Mitchell AG | title = Racemic drugs: racemic mixture, racemic compound, or pseudoracemate? | journal = Journal of Pharmacy & Pharmaceutical Sciences | volume = 1 | issue = 1 | pages = 8–12 | date = 1998 | pmid = 10942967 | doi = | url = https://sites.ualberta.ca/~csps/JPPS1(1)/A.Mitchell/Mitchell.pdf }}</ref>
