GTMolDatabaseUpdate

GTMolDatabaseUpdate[database]
reads database, adds data of another molecule and stores database.

Details Details

Molecular databases have to have a name like "database.parm".
Three methods to update the database are implemented: directly from Mathematica (M), reading data from a file (F) or the direct (D), i.e. interactive input.
If the input from the Mathematica database is chosen, the name of the molecule is asked and the data are added to the database.
If the input from a file is chosen, the file name has to be provided.
During the interactive input the following data are asked step by step: 1. Name of the molecule 2. Formula 3. Formula string 4. Symmetry group of the molecule 5. Reference for the data 6. Remarks to the dataset 7. Number of atoms 8. For each atom the chemical symbol ad the coordinates of the atom:
{chemical symbol, {x,y,z}}

First load the package:

In[1]:=

Prepare a copy of the database for the update example.

In[2]:=

Start the interactive input of new molecular data. Be careful with this example. The application might crash, if you do not go through all the input windows step by step. You can try “CO2” from the Mathematica source.
