Unformatted text preview: decimeter tubes, and you will need to look up the density (g/mL) for each of the (+) and (-) carvones. Should these be the same? Refractive Index You need to place a single drop of your carvone on the lens and adjust the light to get maximum illumination through the eyepiece. There is no need to run water through the sample since our measurements will be close to 20 C. Adjust the coarse/fine knobs on the right side of the refractometer so that the shadow edge is just horizontally even with the center cross-hairs in the eyepiece. Read the refractive index by pressing the button on the left side toward the back. The scale will appear in the eyepiece when the button is pressed. We will not be performing IR, NMR or GC on our samples....
