Descrição: The efficiency of second harmonic generation for melaminium bis(trichloroacetate) was estimated relatively to KDP: deff=3.09deff (KDP). Room temperature FT IR and FT Raman spectra were recorded. Some spectral features of this new crystal are referred to corresponding one for melamine crystal as well as for other trichloroacetates. Differential scanning calorimetric measurements performed on powder sample indicate the phase transition point at approximately 276 and 239K for heating and cooling, respectively.
