we can see that all of the bonds in the structure are sp
bonds (as
expected), since all bonds present in Figs. 7.7a and 7.8a also appear
as dumbbell-shaped surfaces between the atoms. In Figs. 7.7c-f and
8c-f 1(P), 2(P), 3(P), and 3(R) hydrogen atom are adsorbed, and the
changes in the sp
2
network associated with the H adsorption are
evident. Note that C-H bonds are not shown.

configuration.
