Help for Smiles Input:
-
You can input your structure in Smiles format or use the Marvin Sketch application.
- The atom numbering is from left-to-right as listed in the input
Smiles string.
- Examples of Smiles strings:
- 2-Butene: CC=CC
- Ethanol: CCO
- tert-butyl alcohol: CC(C)(C)O
- Cyclohexanol: C1CCCCC1O
- Toluene: c1ccccc1C or C1=CC=CC=C1C
- Acetic acid: CC(=O)O
- Acetamide: CC(=O)N
- Methyl-tert-butyl ether: CC(C)(C)OC
- Nitrobenzene: c1ccccc1[N+](=O)[O-]
- Guanine: Nc2nc1[nH]cnc1c(=O)[nH]2
- Progesterone: CC(=O)C3CCC4C2CCC1=CC(=O)CCC1(C)C2CCC34C
