This review describes the vibrational self-consistent field (VSCF) method and its other
variants for computing anharmonic vibrational spectroscopy of biological molecules. The …

Molecular and Laser Spectroscopy: Advances and Applications provides students and
researchers with an up-to-date understanding of the fast-developing area of molecular and …

We report here infrared spectra of protonated and lithiated valine with varying degrees of
hydration in the gas phase and interpret them with the help of DFT calculations at the …

A comparative study of the metal− glycine bonding for the biologically relevant Cu+ and
Cu2+ pair is presented. The structure and vibrational frequencies for several coordination …

Three bands at 3270 cm− 1, 3200 cm− 1 and 3030 cm− 1 are found in the IR stretching
proton (ν1) mode spectral range in spectra of solid poly-l-lysine (PLL). Strong quantitative …

Na+ and K+ gas-phase affinities of the three aromatic amino acids Phe, Tyr, and Trp were
measured by the kinetic method. Na+ binds these amino acids much more strongly than K+ …

Binding energies were calculated for the complexes of Na+ and K+ with phenylalanine
(Phe), tyrosine (Tyr), and tryptophane (Trp), along with energies of low-energy conformers of …

We present results of the first experimental observation of the nonionized natural amino acid
valine. The study has employed the matrix-isolation IR spectroscopy and the density …

The FTIR spectra of pure and isotopically diluted (H/D and D/H) polycrystalline L-glutamine,
L-hystidine, L-tyrosine, DL-serine, L-threonine, di-, tri-glycine and di-glycine· HCl· H2O salt …

The conformational behavior and infrared spectrum of l-phenylalanine were studied by
matrix-isolation infrared spectroscopy and DFT [B3LYP/6-311++ G (d, p)] calculations. The …
