Having searched for information on inter-atom-distances in organic molecules I found your "Carbon-Carbon-bonds" article interesting as it gave the names of alkanes, alkenes and alkynes for single-, double- and triple-bonds.

Regarding longchain molecules the angles of the bonds and the inter-atom-distances might be of some special interest, if there are variations of Isotope-ratios which will not only cause variations in molecular weight, but also in overall length, flexibility and stereo-isomeric and stereo-isotopomeric properties for recognition on specificity- and lastly immune-relevant levels.

The General Scientific Community Opinion holds the significance of organic isotopes as irrelevant for biologic considerations, but this may be a dogma which might have to be questioned shortly in view of many contemporan problems.

So again : what is known about the interatomic distances and bond strenghts f.i. of C-C bonds, with regard to single-, double and triple bonds and likewise between       -12C-12C-, -13C-12C-, -12C-14C-  and further possible combinations ?

The various bonds will also have varying bond-strengths like 1H-1H < ²D-1H < ³T-1H .. < 1H-16O-... < 2H-18O- ...< 16O-12C-...< 18O-14C-... < ³T-12C- ... < ³T-14C-. Since Linus Pauling had been able to determine the distances and angles between various components of organic material, progress will certainly also have rendered some more details by now like those very interesting bond-strengths between the heavy organic isotopes and their relation to health and aging in case of possible accumulation via modern global food-chains.
