TLDR
In this article, some frequent hazards and problems are addressed and observations of papers reporting amino acid compounds as supposedly new non-linear optical materials are made, as well as observations of articles reporting amino acids compounds as new NLO materials.About:

The effect of carboxylic acids on glycine polymorphism, salt and co-crystal formation. A comparison of different crystallisation techniques
TL;DR: In this paper, the effect of carboxylic acids on glycine polymorphism, salt and co-crystal formation was compared for slow evaporation of solutions at ambient conditions, spray drying, "fast" and "slow" anti-solvent crystallisation and dry co-grinding.
Journal ArticleDOI
Glycine glycinium picrate--reinvestigation of the structure and vibrational spectra.
TL;DR: It was shown that crystals of diglycine picrate obtained from the solution containing equimolar quantities may contain picric acid as impurity, which is the reason for the previously reported observation of second harmonic generation in this centrosymmetric crystal.

Computational, spectral and structural studies of a new non linear optical crystal: 2-hydroxy pyridinium 3,5-dinitrobenzoate
TL;DR: An organic proton transfer compound, 2-hydroxy pyridinium 3,5-dinitrobenzoate (HPDA), was synthesized from 3-5-Dinitro benzoic acid and 2 -hydrox pyridine using methanol:acetone solvent mixture at room temperature and crystallized by solvent evaporation as mentioned in this paper.

Comparative study of CCSD(T) and DFT methods: Electronic (hyper)polarizabilities of glycine
TL;DR: In this article, the static electronic (hyper)polarizabilities of the two lowest energy conformations of glycine have been computed in the gas phase by using high-level ab initio and DFT methods with the POL, LPOLX-ds and LPOL X-fl Sadlej basis sets.
Journal ArticleDOI
On the existence of “l-threonine formate”, “l-alanine lithium chloride” and “bis l-alanine lithium chloride” crystals
TL;DR: It is argued that the recently reported crystals "L-threonine formate" and "bis L-alanine lithium chloride" actually are the well-known crystals L- Threonine and L-Alanine, respectively.

A Powder Technique for the Evaluation of Nonlinear Optical Materials
S. Kurtz,T. T. Perry +1 more
TL;DR: In this article, an experimental technique using powders is described which permits the rapid classification of materials according to the magnitude of nonlinear optical coefficients relative to a crystalline quartz standard and the existence or absence of phase matching direction(s) for second-harmonic generation.
