The torsional energy is seen to have a behavior very similar to the cosine squared dependence on the angle that would be expected if no steric effects were present.
The surface groups of the activated carbon support are responsible for electronic and steric effects during the hydrogenation reaction.
(19c),(22) (3) Applicability of the CGMT model to heavy ethylenes with bulky substituents is less satisfactory because the steric effects are the controlling factor determining the geometry as discussed in the previous section.
The authors concluded that it is possible that ethylene exerts some protection of vinyl acetate units by increasing the steric effects of the polymer backbone through more compact folding, thus leading to more effective shielding of the hydrolyzable units.
In such settings, steric effects and saturation kinetics and effects are probably important.
In a preliminary study (4) using a variety of dibasic acids, including hexahydrophthalic anhydride, anchimeric effects and steric effects were investigated for oligoesters.
Such differences are expected due to surface charge, steric effects, and transport differences.
They pin it on so-called steric effects. In the eclipsed conformation, close carbon-hydrogen bonds crowd each other, thereby raising the molecule's overall energy.
