The Specific Rotation Calculator serves as a valuable tool in scientific analysis, particularly in determining the specific rotation of a substance. It employs a straightforward formula:
α = observed rotation / (c * l)
Here, α represents the specific rotation measured in °/mL/g. The observed rotation indicates the degrees of rotation observed in a sample. The variables ‘c’ and ‘l’ stand for the concentration of the sample in grams per milliliter (g/mL) and the path length in decimeters (dm), respectively. Notably, 1 dm is equivalent to 10 centimeters (cm).
Utilizing this calculator simplifies the calculation process for determining specific rotation, streamlining scientific analyses and research tasks.
General Terms & Conversions Table
For added convenience, here’s a table containing frequently searched terms related to specific rotation:
| Term | Definition/Conversion |
|---|---|

Example of Specific Rotation Calculator
Consider a scenario where a chemist measures the observed rotation of a substance as 24 degrees. The sample has a concentration of 0.5 g/mL and a path length of 2 dm. Plugging these values into the Specific Rotation Calculator:
α = 24 / (0.5 * 2) = 24 / 1 = 24°/mL/g
This result indicates the specific rotation of the substance in degrees per milliliter per gram.
