Fig. 5From: An initial investigation of accuracy required for the identification of small molecules in complex samples using quantum chemical calculated NMR chemical shiftsMean of ranks with respect to the carbon and proton errors and contour lines for the different level of identification ratios when carbons and protons are used together for a, b Set I (water soluble molecules) and c, d Set II (chloroform soluble molecules). b and d are the zoomed versions of a and c, respectively. The color bars represent the rankingsBack to article page
