Pre-lab 8.3 Methods for Measuring Optical Activity

Polarimetry, Optical Rototary Dispersion, and Circular Dichroism Spectrophotometry5,6 

If the rotation is in a clockwise direction, the substance in solution is said to be dextrorotatory [d or (+)]. Rotation in the counter clockwise direction infers a levorotatory substance 

Procedure 8.3 Analysis of the d- and L-Tris(1,10-Phenanthroline) Chromium(lll) Hexafluorophosphate, [Cr(phen)3] (PF6)3, Complexes7,8 

All manipulations must be carried out in the dark (keep aluminum foil on reaction flasks).
