The Chem-Ray Homepage Graphics Options Parameter Selection. When drawings are made in the ball and stick format, this van der Waals radius for each element is multiplied by the atom radius factor. When drawings are made in space filling format, this van der Waals radius for each element is multipled by the van der Waals factor. The bond radius command is used to specify the radius of the bonds in Angstroms in the actual pictures. A small value will give a skinny bond, a large value will give a fat bond.
Strange things can happen if the bond radius is made larger than the atom radii.
The H-bond radius command is used to specify the radius of the hydrogen bonds in Angstroms in the actual pictures. A small value will give a skinny bond, a large value will give a fat bond. Strange things can happen if the H-bond radius is made larger than the atom radii. More meaningful is the size of the font relative to the atoms drawn. Angstroms gives a label that is a nice size relative to the atoms in a picture.
