Pronunciation: myu'ta-ro-ta'shun

Definition: The process of changing specific rotation at a given wavelength; a solution of a-d-glucose recrystallized from its solution in acetic acid and freshly dissolved in water gives a rotation of [a] = +112.2°, but when recrystallized from a boiling aqueous solution (as the ß-form) it shows an initial rotation of [a] = +18.7°; either solution, on standing, slowly changes its specific rotation to a value of [a] = +52.7°, indicating a mixture of the two anomeric forms of d-glucose.

Synonym(s): birotation, multirotation
