Table 2. Average and sample standard deviation (s.s.d.) enrichment ratios in the crystals with Z′ = 2 of alcohol–ketone molecules.

The c correlation coefficients were computed between the two sets of values (, ) and (, ), i = 1⋯17; this way c is independent of the attributions of dimers #1 and #2.
