Reading a frequency calculation output file


If  frequency calculation are present in the OUTCAR  VASP output file, MOLDRAW creates the file OUTCAR_FREQ.MOL under the actual directory and two new options becomes available in the View menu.

 

For very small unit cells it is hard to understand the vibrational modes as too few atoms are involved. In these cases go to the Crystal menu and chose Make Box option. Please also note that, for the way in which MOLDRAW treats periodicity, the options Make cell and Make box are inactive.

 

For further details please refer to the description under by CRYSTAL14 frequencies.
