Fig. 5: HBC in CO···HN and CO···Hα-Cα H-bonds.
From: Hydrogen bonding patterns and cooperativity in polyproline II helical bundles
Mean HBS between the molecules that reproduce each CO···HN (formamide, squares), CO···HαCα front (acetaldehyde, circles), CO···HN + CO···HαCα front (acetamide, diamonds, and dashed line), CO···HαCα inner (acetaldehyde, triangles), CO···HαCα outer (N-methylformamide, inverted triangles) and CO···(Hα)2Cα inner+outer (N-(2-oxoethyl)formamide, hourglass and dashed line) H-bond/interaction. As in the Fig. 1C color scheme, the ab interface for the different systems is indicated in blue; the bc interface, in red, and the cd interface, in green.
