The series of phase transitions on increasing pressure and on reverse decompression was
followed in crystals of monoclinic and orthorhombic polymorphs of L-cysteine by using …

Several amphoteric model compounds and drugs, such as isomers of aminobenzoic acids
(ortho, meta, and para), N-aryl-2-amino-nicotinic acids (three isomers), amino-salicylic acids …

One of the most important industrial requirements is to find the materials which have the
tendency to withstand harsh environments, such as high pressure, high temperature, and …

Pressure-dependent Raman studies were preformed on two dimethylammonium metal
formates,[(CH 3) 2 NH 2][Mg (HCOO) 3](DMMg) and [(CH 3) 2 NH 2][Cd (HCOO) 3](DMCd) …

DL-Norvaline is a molecular crystal at room temperature and it undergoes a phase transition
when cooled below 190 K. This phase transition is believed to be Martensitic, thus making it …

Raman spectroscopy was used to investigate the vibrational properties of l-glutamic acid in
the β-form in a diamond-anvil cell up to pressures of 21.5 GPa in the spectral region …

Amino acids are among the earliest organic molecules to exist on Earth, and the origin of
such bio-molecules on Earth is still a topic of intense discussion in the associated scientific …

We report here the results of our high pressure infrared absorption investigations on Bis
(glycinium) oxalate, an organic complex of glycine. The observation of Raman active modes …

We have obtained the Raman spectra of dl-leucine crystal through a diamond anvil cell for
pressures between 0 and 5GPa. The observation of several anomalies in the regions of both …

Single-crystals of l-histidine hydrochloride monohydrate, C6H9N3O2· HCl· H2O, were
studied by Raman spectroscopy as a function of pressure in a diamond anvil cell up to 7.5 …
