The Molymod short v-link is used in semi-spacefilling models to compensate for small angular differences in non-standard vsepr shapes. It is especially important for accommodating uncommon bond angles. This is best seen in our 17 base pair DNA model, first sold to Bell Labs in 2000 & 36 base pair "Big Bang Theory" DNA molecular model.
Note: the Big Bang Theory Model as seen on TV used 2 of the 17 base pair versions stacked together.

These V-bonds are found in teachers' sets. If you are a student, these bonds come in handy when building closed-dome [spacefilling] models of pentagons as seen in DNA nucleotides of adenine and guanine. These components can supplement a student's molecular set. Other [rare] uses include Polycyclic Aromatic Hydrocarbons (PAH) or Heterocyclic compounds...
