The requirements for optical rotation and specific rotation apply to the dried, anhydrous, or solvent-free material in all those monographs in which standards for loss on drying, water, or solvent content are …

Racemates have a net null optical rotation, and their physical properties may differ from those of the component enantiomers. Use of stereoselective or stereospecific syn-thetic methods or separation of …

Optical rotation is considered to be positive (+) for dextrorotatory substances (i.e. those that rotate the plane of polarisation in a clockwise direction) and negative (−) for laevorotatory substances.

There are many different ways to characterize optical rotation and circularly dichroism, as illustrated in the following table. We can determine the representation of different secondary structures in a …

In characterizing the accuracy of the DFT methodology in calculating optical rotations, it is important to use a large and diverse set of molecules, so that meaningful statistics can be obtained.

Having described optical rotation in terms of the index of refraction, we must now find a relationship between an applied magnetic field and its effect on the optical properties.

OPTICAL ROTATION AND ITS APPLICATION. Polarimetry is one of the important instrumental methods employed in analysis. This measure the rotation of the polarized light as it passes through …
