Simulating IR spectra w/ MOPAC



 Dear Colleagues;
      I am given to understand it is possible to simulate or approximate
 and IR spectrum using output obtainable from the programme MOPAC.  I would
 like to very roughly predict some peaks in IR spectra of some compounds of
 interest.  Can anyone provide me with step-by-step instructions on how to go
 about simulating an IR spectrum using MOPAC?  I have considerable experience
 with MOPAC for other calculations, but not for IR simulation.
      Thanks in advance to all responders.
 Sincerely,
