Structural and thermal characterization of a semiorganic NLO material: l-alanine cadmium chloride

Growth and characterization of pure and lithium doped L‐alanine single crystals for NLO devices

“…[13]. The NH 2 group of Lalanine is protonated by the COOH group, giving rise to NH 3 + and COO -groups [14]. In the overtone region, there is a sharp intense peak at 2112.44 cm -1 which is assigned to combinational and asymmetrical bending vibration of NH 3 + .…”

Growth of Organic Nonlinear Optical Crystals from Solution

“…The characteristics vibration of LAS has been compared with L-alaninium alanine nitrate (Aravindan et al, 2007) and L-alanine cadmium chloride (Dhanuskodi et al, 2007) as shown in Table 3. The asymmetric stretching vibration of NH 3 + is observed at 3086 cm −1 of LAS is confirming the presence of NH 3 + in compound.…”

Spectral Characterization, Dielectric, Mechanical and SHG Studies of Thiourea Doped L-Alanine Cadmium Chloride Crystals

“…In amino acid based metal organic complexes, the organic ligand is usually more dominant in the NLO effect. As for the metallic part, focus is on the metals like Zn, Cd and Hg as these compounds usually have a high transparency in the UV region, because of their closed d 10 shell. Potential NLO materials [3] like bisthiourea cadmium chloride (BTCC), triallylthiourea cadmium chloride (TATCC) have been studied.…”

“…Several new complexes incorporating the amino acid L-alanine have been recently crystallized and their structural, optical and thermal properties have been investigated [6][7][8][9]. L-alanine cadmium chloride was first synthesized by Kathleen et al [10] and later its properties were studied by Dhanuskodi et al [11]. Bright et al have reported the frequency and temperature dependence of dielectric properties of L-alanine cadmium chloride [12].…”
