Dynamics in low temperature glasses: Theory and experiments on optical dephasing, spectral diffusion, and hydrogen tunneling
TL;DR: In this article, temperature dependent photon echo (PE) and nonphotochemical hole burning (NPHB) measurements were reported on resorufin in three organic glasses: ethanol (1.5 −11 K), glycerol (1 −1 −25 K), and d−ethanol (1−1−11 K).

Proton transfer in benzoic acid crystals: A chemical spin–boson problem. Theoretical analysis of nuclear magnetic resonance, neutron scattering, and optical experiments
TL;DR: In this paper, the double minimum potential of the spin-boson Hamiltonian was analyzed in NMR T1 relaxation experiments and the temperature-dependent proton transfer rate that emerges from the NMR analysis was in good agreement with inelastic neutron scattering experiments.
Journal ArticleDOI
Hydrogen bond dynamics in isotopically substituted benzoic acid dimers
TL;DR: In this paper, the authors investigated the hydrogen pair transfer in the hydrogen-bonded dimers of benzoic acid and its carboxyl-deuterated species in the solid.

Structure and Dynamics in Solids As Probed by Optical Spectroscopy
James L. Skinner,W. E. Moerner +1 more
TL;DR: The spectral properties of individual single impurity molecules in a solid can be measured, with all ensemble averaging removed as discussed by the authors, which has provided additional information on a highly local scale, such as the direct observation of the spectral shifting of a single molecule.

Toward Elimination of Discrepancies between Theory and Experiment: Double Proton Transfer in Dimers of Carboxylic Acids
Thomas Loerting,Klaus R. Liedl +1 more
TL;DR: In this paper, a dual-level reaction path dynamics calculation of the synchronous proton exchange in carboxylic acid dimers is presented, which is consistent with a wide variety of experimental findings, such as reaction rates k, tunneling splittings Δ0, apparent activation energy curves Ea (T), crossover temperatures Tc and kinetic isotope effects.

Structure and dynamics of intramolecular hydrogen bonds in carboxylic acid dimers: A solid state NMR study
TL;DR: In this paper, an asymmetric double minimum potential with an energy difference ΔG = 1.0 kJ/mol and an activation energy of Ea = 4.8 kj/mol between the two tautomeric forms is found.
Journal ArticleDOI
An NMR relaxation study on the proton transfer in the hydrogen bonded carboxylic acid dimers
TL;DR: In this article, the authors studied the proton spin-lattice relaxation times (T1) of a series of benzoic acid derivatives and decanoic acid over a wide range of temperature and analyzed the results in terms of double proton switching along the hydrogen bonds.
Journal ArticleDOI
A study on the proton transfer in the benzoic acid dimer by 13C high-resolution solid-state NMR and proton T1 measurements
TL;DR: In this article, a solid-state 13C and proton NMR study of the hydrogen-bonded dimer of benzoic acid was performed and the rate of proton transfer, the height of the potential barrier for the transfer and the relative population of two different configurations were determined.

Disappearances of COOH infrared bands of benzoic acid
S. Hayashi,J. Umemura +1 more
TL;DR: In this paper, the infrared spectra of benzoic acid and benzosic acid d were obtained in the range of temperatures from liquid nitrogen to liquid helium and the C=O stretching band at 1688 cm−1, the strongest absorption band of this compound in the over-all infrared region at room temperature, decreases in intensity with decreasing temperature.
Journal ArticleDOI
Direct studies of proton tunneling in hydrogen bonded mixed molecular crystals by optical excitation
TL;DR: In this article, the authors measured the site interconversion process of thioindigo in benzoic acid host crystals at 1.4-4.2 K and showed that the sites arise from different tautometic forms of neighboring host dimer molecules.
