Optical rotation is a fundamental phenomenon observed when plane-polarised light traverses chiral media. This intrinsic property of chiral molecules renders them capable of rotating the plane of ...

Basic polarimeters are comprised of a light source, two polarizing filters, an eyepiece for direct observation of optical rotation and a sample tube containing a solvent of interest. This phenomenon ...

Physicists in Italy have demonstrated that empty space can cause light to rotate in the presence of a large magnetic field. Although the effect seen by Emilio Zavattini and co-workers on the PVLAS ...
