Dear all, 

I'd like to compute the vibrational modes of an organic molecule that has 
been adsorbed on a metal surface. The count works appropriately with the 
isolated molecule, but when I include the surface, I am unable to complete 
the vibrational study due to the time limit of 24 hours. Is it possible to 
restart the calculation, especially the frequencies? I've attached my 
input. Thank you for your assistance.

Best 

Lorenzo Briccolani
