Identification of Localized Bonds in the Hydrocarbons

From measured Compton profiles of C${\mathrm{H}}_4$, ${\mathrm{C}}_2$ ${\mathrm{H}}_4$, and ${\mathrm{C}}_2$ ${\mathrm{H}}_6$, experimental values are found for the Compton profiles of C-H, C-C, and C=C bonds. These profiles are then used successfully to predict within experimental accuracy the measured Compton profiles of ${\mathrm{C}}_3$ ${\mathrm{H}}_6$, ${\mathrm{C}}_6$ ${\mathrm{H}}_6$, ${\mathrm{C}}_6$ ${\mathrm{H}}_{12}$, ${\mathrm{C}}_6$ ${\mathrm{H}}_{14}$, and ${\mathrm{C}}_8$ ${\mathrm{H}}_{10}$. This success is strong evidence that the identified C-H, C-C, and C=C bonds are indeed localized and transferrable.
