# softmatter:Israelachvili packing factor

From NSDL Materials Digital Library Wiki

The geometry of associated structures depends upon "packing" properties of the molecule: the optimal area of the head group, **a _{0}**, volume of the chain,

**V**, and the critical length of the tether,

**l**.

_{c}By relating these quantities, we arrive at the *Israelachvili packing factor* =
