[QE-users] No IR vibrational peak

[홍장희]

Hi,

I was calculated ice cluster's vibration using ph.x.

but no IR peaks appeared.

I don't know the reason.

here my input & output

Normal modes for Wurtzite
 &inputph
  tr2_ph=1.0d-14,
  prefix='ice_scf',
  outdir='./out/'
  epsil=.false.,
  trans=.true.,
  asr=.true.
  fildyn='dmat.ice'
 /
 0.0 0.0 0.0


Thanks
