“…IR spectroscopic data are assigned and compared with known ones ofsimple amino acids and arginine-and alaninecontaining peptides. 26 A multiple band in the 850-550 cm (Table II) in the same dichroic ratio indicated a colinearity of their transition moments, which is in agreement with the theoretical structure [ Figure 3(3)] as well. However, the last procedure provoked an elimina-FIGURE 3 Nonpolarized IR (1) and reduced IR-LD spectra of GGArg after elimination of 3288 cm -1 (2) and 3080 cm -1 (3) peaks.…”

Structural prediction and IR-characteristic bands assignment of arginine-containing tri- and tetrapeptides glycyl-glycyl-arginine (GGArg) and glycyl-glycyl-arginyl-alanine (GGArgAla) have been carried out, using linear-dichroic infrared (IR-LD) spectroscopy of oriented solid-samples in a nematic liquid crystal suspension. Spectroscopic data have been supported with ab initio analysis (Hartree-Fock level of theory and 6-31++G** basis set). Predicted geometry parameters have been compared with known crystallographic ones of similar peptides, indicating a good correlation.

“…Related to the first point we remember that Raman spectroscopy study have suggested the occurrence of a phase transition undergone by LAHW crystal at about 110 K [8]. This phase transition was inferred mainly by the change of band profiles in the low-wavenumber region of the spectra.…”

“…It was observed that under high temperature conditions LAHW begins to lost water of crystallization at 70 o C and at 200 o C about two-third of it are eliminated [7]. Under low temperature conditions, on the other hand, it was observed through Raman scattering technique, evidence of a phase transition undergone by LAHW between 100 and 110 K [8]. Although in the paper of Ref.…”

Such assignment is very important because it helps us to understand what vibrations are related to the crystal modifications, in particular under temperature and pressure changes.…”

Polarized Raman spectra of L-arginine hydrochloride monohydrated single crystal in nine different scattering geometries of the two irreducible representations of factor group C 2 were studied at room temperature. The experimental wavenumber values are compared with those obtained from ab-initio calculation and the assignment of the Raman bands to the respective molecular vibrations is also given. Finally, a discussion related to a previously reported phase transition undergone by L-arginine hydrochloride monohydrated single crystal at low temperature is furnished.

“…The vibrational spectra of systems with hydrogen bonds are important sources of information on the dynamics and nature of the interaction. 12 Hammer et al 36 studied the single-crystal IR spectroscopy of very strong hydrogen bonds in pectolite and serandite. Foglizzo and Novak 37 reported the low-wavenumber infrared and Raman spectra of hydrogen-bonded pyridinium halides.…”

The Raman and infrared absorption spectra of 2(C 5 H 14 N 2 O 2 2+ )·Cl − ·NO 3 − ·SO 4 2− crystal containing three anions were recorded at room temperature and were interpreted in the light of crystal structure data. The presence of a carbonyl group was identified. The carboxylic group was found to exist as COOH. The formation of O -H· · ·O, N -H· · ·O and N -H· · ·Cl asymmetric hydrogen bonds contributes considerably to the crystal cohesion and is responsible for the changes in the position and intensity of several bands. The vibrational spectra show that the anions were found to coordinate through hydrogen bonding interactions to other ligands in the crystal. The lattice wavenumbers of the halide radical (chlorine anion) were also assigned in terms of hydrogen bond vibrations.
