The δC trajectories for the 10 carbon atoms in exo-TCD chair and boat isomers in In contrast, the other three hydrogens-H(15) on C5 and H , H(26) on C10-exhibit greater sensitivity to the structural changes, particularly as the boat configuration is approached. The chemical environments of H and H( ) are more similar in the exo-chair configuration, reflecting the more symmetrical and stable structure. However, as the boat-tip shifts towards the flag carbons, the chemical environments of H and H(26) on C10 become more alike in the exo-boat configuration. This suggests that in the boat form, the spatial arrangement of these hydrogens becomes more congruent, leading to similar shielding or deshielding effects in the NMR spectra.
