Draw your compound below, or skip to Step 2 if you already know its SMILES string. Step 2 will generate two input files that must be run in Gaussian 09 (optimisation and frequency calculations in gas and solution phases).
You can change atoms and bonds by selecting them and using the popped up options. Skip to Step 2 if you already know its SMILES code.
Either transfer structure from Step 1 or write your own SMILES string. Select your solvent and method, and download your Gaussian 09 input files.
This model is intended for small organic uncharged molecules (MW < 500 Da); currently mixtures or salts are not supported.
DFT selects b3lyp/6-31+G(d) method; PM6 selects PM6, a semi-empirical method. PM6 is much faster but some loss in accuracy may occur.
