29. Note that there are three distinct types of CH⋯O interactions discussed. In the adenine-uracil/thymine base-pair, the 1-1 dimer, and the intramolecularly hydrogen-bonded 2 the CH group is adjacent to two, one, and no nitrogen atoms, respectively. More flanking nitrogen atoms should make for a more acidic C - H group and a correspondingly stronger CH⋯O hydrogen bond.

31. Other plausible explanations exist for the unusual stabilities reported herein. For example, differences in primary hydrogen bonding strengths, differences in the strength of the intramolecular hydrogen bond in 2 and 3, dipolar interactions, differential solvation, etc. may explain the results. These effects, although potentially quite important, are less readily discernible.
