A
perspective formula indicating the spatial arrangement of bonds on two adjacent carbon atoms. The bond
between the two atoms is represented by a diagonal line, the left-hand bottom end
of which locates the atom nearer the observer and the right-hand top end the atom
that is further away. In general a
Newman or
zig-zag projection is preferred.
