A form of solution-phase Raman spectro·scopy named for this molecular property reports a value called C·I·D. This quantity is unexpectedly zero for the molecule N-butyl·ethyl-N-hexyl-N-propyl·methane. Greater values for this property of a cholesteric (“COAL-uh-steer-ick”) mesogen allow proportionally thinner films to be used in LCDs. Food scientists measure this property as a quality check on the concentration of sugar in syrup. (-5[2])This quantity is traditionally reported at the sodium D line, but since it’s the Kramers–Kronig transform of ellipticity, its dispersion is reported by circular di·chroism. Specific (10[1]-5[1])values for this quantity are symbolized by an alpha (-5[1])in (10[1])brackets. (-5[1])To indicate the (10[1])sign (10[1])of this quantity, (10[1])IUPAC (“I-U-pack”) now prefers pluses and minuses to the archaic (-5[1])prefixes (-5[1])D and L. (10[1]-5[3])For 10 points, enantio·meric (-5[1])excess (-5[1])is calculated by using a polarimeter to measure what angle, (-5[1])which is only nonzero for chiral molecules? (10[2])■END■ (10[4]0[5])
