I do not think so. LO-TO splitting originates from the long
range coulomb interaction and ordered dipole vibration. The latter
does not exist in molecular.
> My Further qusetion regarding the RAMAN modes. Whether pure Raman modes (i.e.
> Infrared inactive modes and only Raman acive) will give any LO-TO splitting.
