In the first part of this work, we report the FTIR spectra of pure NH and isotopically substituted ND (10–15% D and 80–90% D) polycrystalline hypoxanthine, xanthine, adenine and guanine recorded in the 400–4000 cm−1 range, as a function of te

FTIR and NMR spectra were measured in parallel for specific two-components mixtures of various proteins with different sugar molecules, such as arabinose, glucose, and sucrose. In the FTIR spectra of arabinose with some of these proteins, the bands a

The infrared spectra of formic acid/argon matrix layers deposited after flowing over a drying agent show distinct new bands when compared to matrix layers deposited without going through a drying process. The new bands are assigned as due to a formic

Frozen core MP2 and DFT computations were carried out on possible configurations of 1:1 H2SO4·CH3OH and 1:1:1 H2SO4·CH3OH·H2O complexes. Minimum energy structures, stabilization energies, H-bond lengths and vibrational frequencies were calculated.

A new correlation ν 3 = 1997 + 1.17 × 10 3 Δ r between the stretching mode ν 3 of the IR band frequency and the bond length asymmetry expressed as Δ r ≡ r (N α − N β ) − r (N β − N γ ) is established in molecular azides R N α N β N

The FTIR matrix isolation spectra of H2SO4 vapors show a group of bands with synchronous growth of their relative intensities which is independent of the water species content of the matrix layer. Their frequency positions indicate that the species t

Poly(4-vinylpyridine) swollen in pyridine displays changes in electrical conductivity in response to white light and to low level thermal perturbation; protonation of the side-chain nitrogen is believed to play a role. Here we present spectroscopic e
