Pronunciation: myū′tă-rō-tā′shŭn

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

Synonym(s): birotation, multirotation
