Dear CCLs

In B3LYP calculations with different Key words,I got three SCF energies
	(the symmetry is D{inf}h ):

	Key words       energies(Hartree)
	opt           -285.765847272
 	freq          -285.765847272 (guess=read from opt)	          (1)
	stable=opt    -285.782563187
	freq          -285.055421726 (guess=read from stable=opt)     (2)

	I think this freq(2) calculation is wrong,because it has a bigger energy
	and a virtual vibrational frequencies. Does the freq(1) give 
	the correct vibrational frequencies ?

    Thank you for your help!
