Characterization of fluxional hydrogen-bonded complexes of acetic acid and acetate by NMR: geometries and isotope and solvent effects.
1H, (2)H, and (13)C NMR spectra of enriched CH(3)(13)COOH acid without and in the presence of tetra-n-butylammonium acetate have been measured around 110 K using a liquefied Freon mixture CDF(3)/CDF(2)Cl as a solvent, as a function of the deuterium fraction in the mobile proton sites. For comparison, spectra were also taken of the adduct CH(3)(13)COOH.SbCl(5) 1 and of CH(2)Cl(13)COOH under simi...
متن کاملCoherent low-frequency motions of hydrogen bonded acetic acid dimers in the liquid phase.
Ultrafast vibrational dynamics of cyclic hydrogen bonded dimers and the underlying microscopic interactions are studied in temporally and spectrally resolved pump-probe experiments with 100 fs time resolution. Femtosecond excitation of the O-H and/or O-D stretching mode gives rise to pronounced changes of the O-H/O-D stretching absorption displaying both rate-like kinetic and oscillatory compon...
متن کاملTwo-dimensional hydrogen-bonded polymers in the crystal structures of the ammonium salts of phenoxyacetic acid, (4-fluorophenoxy)acetic acid and (4-chloro-2-methylphenoxy)acetic acid
The structures of the ammonium salts of phen-oxy-acetic acid, NH4 (+)·C8H6O3 (-), (I), (4-fluoro-phen-oxy)acetic acid, NH4 (+)·C8H5FO3 (-), (II), and the herbicidally active (4-chloro-2-methyl-phen-oxy)acetic acid (MCPA), NH4 (+)·C9H8ClO3 (-)·0.5H2O, (III) have been determined. All have two-dimensional layered structures based on inter-species ammonium N-H⋯O hydrogen-bonding associations, which...
متن کاملConformational effects and level mixing in a doubly hydrogen-bonded 1 : 1 dimer of acetic acid and 3-fluorobenzoic acid
Vibronically resolved S1 ↔ S0 electronic spectra of a doubly hydrogen-bonded mixed dimer between acetic acid and 3-fluorobenzoic acid have been investigated by measuring laser-induced fluorescence excitation and dispersed fluorescence spectra in a cold supersonic jet expansion. Two isomeric species of the dimer have been identified, and the measurements show that their vibronic spectral pattern...
متن کاملHydrogen-bonded dimer stacking induced emission of aminobenzoic acid compounds.
A series of aminobenzoic acid crystals with stacking-induced emission properties has been achieved and the packing structures of the hydrogen-bonded acid dimers provided an explanation for the emission characteristics of the crystals.
