摘要

Powder Kurtz-Perry measurements were performed for the title crystals. The efficiencies of second harmonic generation were determined (0.34, 0.84, 0.80, 0.97 and 1.01) relative to potassium hydrogen phosphate. The L-lysine moiety was characterized by wavenumbers and relative intensities of the infrared and Raman bands originating from internal vibrations. The presence of hydrogen bonds in the studied crystals is noted and the potential role of this type of intermolecular interaction in the second harmonic generation phenomena is discussed.
