It means substance is optically inactive ,it is either a Recemic mixture or a Meso form of a compound
by this law specific rotation =degree of rotation /concentration of a substance *length of sample tube
The specific rotation of amoxicillin is approximately + 203° (c=1, water).
The specific rotation of a compound is calculated using the formula: Specific Rotation Observed Rotation / (Concentration x Path Length) Where: Observed Rotation is the angle of rotation measured in degrees Concentration is the concentration of the compound in grams per milliliter Path Length is the length of the tube or cell through which the light passes in decimeters By plugging in these values into the formula, you can calculate the specific rotation of a compound.
To calculate the specific rotation of a compound, you need to measure the observed rotation of a solution of the compound in a polarimeter, and then use the formula: specific rotation observed rotation / (concentration x path length). The observed rotation is the angle of rotation measured in degrees, the concentration is the concentration of the compound in the solution in g/mL, and the path length is the length of the polarimeter tube in decimeters.
The specific rotation of S-carvone is +61.3. When a sample of R-carvone with 85% enantiomeric excess (ee) has a specific rotation of -54, it means that 85% of the sample is R-carvone (which has a specific rotation of -61.3) and 15% is S-carvone.
by this law specific rotation =degree of rotation /concentration of a substance *length of sample tube
The instantaneous center of rotation is a point in a rigid body that has zero velocity at a specific moment in time. It is the point around which all parts of the rigid body have rotation at that moment. It helps to analyze the motion of the rigid body at that instant.
The specific rotation is +123 and -123 degrees for the (+) and (-) enantiomers respectively
