The R-Group Fragments Palette


The R-Group Fragments window allows you to select from a series of AM1-optimized functional group fragments. It is illustrated below. The default group is carbonyl (formaldehyde).

The R-Group Fragments Palette

Use this palette to select the desired functional group.

Note that several of the fragments use non-traditional bonding. These fragments include a five-member ring with an open bond perpendicular to the plane of the ring: an n5-cyclopentadienyl ligand for use in constructing organometallic systems (circled above).
