The thickness of the substance the concentration of the solution (gm/cc) temperature and, the wavelength of light used The optical activity of a substance is measured by its specific rotation (or specific rotatory power)Optical Rotation Report David Barba González (and Martin Bluck) L2 ResearchLed Investitagion, Lab Day Thursday Date of Experiment 6 Weeks from the 5th of February to the 13rd of March Abstract The aim of the experiment performed was to give an insight into the phenomena of optical rotation of monochromatic light through a polarizing filter and optical activity of sucrose andQuestion 1 Download Solution PDF A sugar solution in a tube of length dm produces optical rotation of 12° Then, the sugar solution to one half of its initial concentration If the dilute solute solution is contained in another tube of length 30 dm, the optical rotation produced by it
In which θ is the optical rotation produced by the solute, C is the solute concentration conventionally measured in g cm –3 units and L is the optical path length through the solutionOptical Activity Optical activity of an organic compound refers to the property of an organic compound by the virtue of which, it rotates the plane polarized light (produced by passing ordinary light through Nicol prism) when it is passed through their solutions and the compounds are known as optically active compounds The optical activity of the substance is a measure of the abilityIf the optical rotation produced by ref image I is 3 6 ∘, then the optical rotation produced by ref image II Medium Answer Since the rotation caused by chiral centre is cancelled by the other, it is a meso compound
Optical Rotation The plane polarised light which is produced by passing ordinary light through Nicol prism is rotated by certain compounds when it is passed through their solutions Such compounds are known as optically active compounds The polarimeter is used to measure the angle by which the plane polarised light is rotated The angle of rotation produced by any optically active substance depends on some factors;Optical rotation produced by atoms in a magnetic field An earlier theoretical treatment of optical rotation in a dilute atomic vapour caused by an applied magnetic field is extended to give results for any orientation of the field with respect to the direction of propagation of the light and the direction of its electric vector

An apparatus for measuring optical rotation produced by optically active substances is described in which light, after passing through a continuously rotating Polaroid disk, carrying a degree scale, then goes through a stationary Polaroid disk and is incident as sinusoidally modulated light upon a phototube, causing it to produce a signal (of audiofrequency twice that of the frequency ofHence, the quantity governing the amount of rotation is the rotatory strength R = Im(dtlm10>) can have a substantial rotatory power ifOptical Rotations, Refractive Indices, and Densities of Dextran Solutions 1 C F Snyder, H S Isbell, M R Dryden, and N B Holt Clinical dextrans obtained from commercial sources, using different strains of Leuconostoc mesenteroides, ,,"ere found to vary in optical rotation (ra ~g;3CA) from 19
