RM1BH calculations can be very easily carried out in MOPAC2009 by using the keyword RM1 and passing the parameters in file RM1BH.rm1 via the keyword EXTERNAL, as follows:

  1. Download, unzip, and copy the file RM1BH.rm1  to the same folder where your MOPAC input .mop file is;
  2. In the first line of the input .mop file, use both keywords RM1 and EXTERNAL=RM1BH.rm1     

That is it! Your calculations will now be MOPAC2009 RM1BH calculations.
