Atom-coded ball and wire frame display. Cylindrical bonds colour coded for bond-order. Renumber structure using Morgan's algorithm Find molecular formula, molecular weight, and masses of molecular ions in mass spectrum. Any one of the structures A, B, C, D may be copied into any of the others. The pairs of structures A and B, or C and D, may be merged to give a composite structure.
Indication is given to the operator of unacceptable non- bonded interactions.
Merging can be controlled so that a specified distance between atoms in the two structures may be met. A previously made structure can be recalled and further modified. The current structure can be stored away at any time. The option of undoing the last operation is provided, so allowing mistakes to be rectified. This process usually takes only a few seconds.
