Preferred Label : bisecting conformation;
Detailed label : bisecting conformation (eclipsing conformation);
IUPAC definition : For a structure containing the grouping R sub 3 /sub C–C(Y) X (with identical or different
groups R) the conformation in which the torsion angle is such that X is antiperiplanar
to one of the groups R, and, in a Newman projection, the double bond C X bisects one
of the R–C–R angles. In this conformation the bond C–Y eclipses one of the C–R bonds.
The other conformation, in which X is synperiplanar to one of the groups R, is called
an eclipsing conformation.;
