## Abstract

Laser Raman spectra were recorded for $KClO_4$, $RbClO_4$, and $CsClO_4$ for all 6 necessary orientations in the range 50-1200 $cm^{-1}$. In the 50-400 $cm^-1$ region the low frequency lines are attributed to lattice vibrations whereas the high frequency lines are librational. In the 400-1200 $cm^{-1}$ region the cation effects on $ClO_{4-}$ frequencies is insignificant. The doubly degenerate vibration \nu$^2$ does not show any splitting. The triply degenerate vibration $\nu$s shows a splitting ranging from 28 to 40$cm^{-1}$.
