VLVL(5) Vocabulary

This occured to me as well, but so long as all the
rooms on the four segments of the X have windows
facing the ocean, they could conceivably all have an
ocean view.  Helps if the hotel is situated thus ...

The dihedral angle can be defined by a set of four
atoms independent of the molecular structure. In
particular, the four atoms do not have to be connected
to each other. Each atom is selected by a separate
selection statement. The dihedral angle involving four
atoms i,j,k,l is defined as the angle between two
planes, where the first plane is made by atoms i,j,k
and the other plane is made by atoms j,k,l.
