[Pw_forum] about the influence of lo-to split on the vibrational model

[xu yuehua]

hi everyone :
 i am now computing ir-intensity.and  in the input  file, i add  lo-to split
.and the result is that some vibration frequency is changed corresponding to
the *.dynG.
and my question is once adding lo-to split,does the vibrational model
including vibrational vector changed ?if it does ,how to get the changed
vector ,because i need to plot the   graph about  the mode .
maybe some of you could give me a piece of advise.
i need your help
thank you
