WebThe ability of a solution to rotate plane-polarized light in this fashion is called optical activity, and solutions which have this ability are said to be optically active. Figure %: Rotation of plane-polarized light by optically active compounds Using a technique called polarimetry, optical activity is measured by a device called a polarimeter. WebA non-optically active member of a collection of stereoisomers, of which at least two are optically active, is known as a meso compound or meso isomer. This means that despite having two or more stereogenic centres, the molecule is not chiral. They’re achiral compounds, meaning they feature several chiral centres. ...
