I'm trying to run Polarizable Continuum Model (PCM) calculations using the GAMESS(US) software. I'm not that well versed in what exactly these calculations are doing (beyond the whole, 'gas within a solvent cavity' explanation). So I will preface and say the calculations might be working and I am simply not understanding the results.
I am running a simple calculation just to start understanding PCM calculations, so I'm using this input:
! AutoGAMESS Version 1.1.8 ! by Brian C. Ferrari ! $CONTRL SCFTYP=RHF MULT=1 NPRINT=0 COORD=UNIQUE RUNTYP=HESSIAN ICUT=12 ITOL=25 DFTTYP=B3LYP MAXIT=200 QMTTOL=1E-7 ICHARG=0 ISPHER=1 $END $SYSTEM MWORDS=800 MEMDDI=800 $END $STATPT OPTTOL=1E-6 NSTEP=200 $END $PCM SOLVNT=CH3OH $END $FORCE METHOD=SEMINUM NVIB=2 PROJCT=.TRUE. $END $SCF DIRSCF=.TRUE. FDIFF=.FALSE.

The calculation terminates normally but the results it prints out are the following:
MODE FREQ(CM**-1) SYMMETRY RED. MASS IR INTENS. 1 0.000 A 12.000000 0.001636 2 0.000 A 12.000000 0.001636 3 0.000 A 12.000000 1.444876 4 0.000 A 15.994910 0.001228 5 0.000 A 15.994910 0.001227 6 0.000 A 15.994910 1.084002
This seems like garbage to me, since the frequencies are all 0 but there are some IR intensities. Which leaves me wondering what is going wrong to cause this error in the calculation? What should I change in the input file?
