Specific Rotation - Chemistry Steps

Webthe temperature are indicated immediately after the symbol for specific rotation. For example, the specific rotation for (R)-2-methyl-1-butanol using the D line from a sodium lamp (589 nm) at 20 °C is reported as follows: In this activity, the specific rotation of a commonly available chiral molecule, sucrose, will be determined. WebFor example, if the specific rotation of the R enantiomer is +8.40 o, then the mixture containing 60% R will have a specific rotation of +8.40 o x 0.20 = +1.68 o. The 0.20 is the enantiomeric excess (60-40=20%). This means that the specific rotation of this sample is 20% of the specific rotation of the R enantiomer.
