Raman spectrum of lithium ammonium tartrate monohydrate

Summary

Using λ2537 resonance radiation as exciter, the Raman spectrum of a single crystal of lithium ammonium tartrate has been recorded for the first time. The spectrum exhibits thirty-seven Raman lines. The observed frequency shifts are compared with those of other tartrates. The frequencies due to the NH₄ ion are seen to be very much suppressed in the spectrum of this crystal.

A few of the Raman lines show marked variations in intensity with orientation of the crystal.
