Is Dissociation of HCl in DMSO Clusters Bistable? [PDF]
, 2021 The dissociation of HCl embedded in DMSO clusters was investigated by projecting the solvent electric field along the HCl bond using B3LYP-D3/6-31+G(d) and MP2/6-31+G(d,p) levels of theory.

Dissociation Rate Calculation via Constant-force Steered Molecular Dynamics Simulation [PDF]
, 2022 Steered molecular dynamics (SMD) simulations have been applied to molecular dissociation events by adding a harmonic force to molecules. Further, molecules are pulled at a constant velocity.

Bond dissociation energies of X–H bonds in proteins [PDF]
, 2022 Knowledge of reliable X–H bond dissociation energies (X = C, N, O, S) for amino acids in proteins is key for studying the radical chemistry of proteins. X–H bond dissociation energies of model dipeptides were computed using the isodesmic reaction method ...

Prediction of Dissociation Constant in Protein-Ligand Interaction [PDF]
, 2021 In protein-ligand interactions, such as antigen-antibody interactions and hormone-receptor interactions, a correlation between the equilibrium dissociation constant KD and the reduced mass of the protein and ligand was found.

The Historical Development of the Words “Dissociation” and “Ionization” in Chemistry
Revista Debates em Ensino de Química, 2023 The words "dissociation" and "ionization" are sources of misconceptions in chemistry teaching, mainly in the subjects of acids and bases, chemical equilibrium and solutions. In the present article, the historical development of the two words was analyzed.

Dissociation Chemistry of Hydrogen-Deficient Radical Peptide Anions [PDF]
Journal of the American Society for Mass Spectrometry, 2011 The fragmentation chemistry of anionic deprotonated hydrogen-deficient radical peptides is investigated. Homolytic photodissociation of carbon-iodine bonds with 266 nm light is used to generate the radical species, which are subsequently subjected to collisional activation to induce further dissociation.

Cosmic Ray Dissociation of Molecular Hydrogen and Dense Cloud Chemistry [PDF]
Research Notes of the AAS, 2020 Abstract Dissociation of molecular hydrogen by secondary electrons produced by cosmic ray or X-ray ionization plays a crucial role in the chemistry of the densest part of molecular clouds. Here we study the effect of the mean kinetic energy of secondary electrons on this process. We compare predictions using a range of secondary electron

Impact of acidity and surface-modulated acid dissociation on cloud response to organic aerosol [PDF]
Atmospheric Chemistry and PhysicsAcid dissociation of the organic aerosol fraction has the potential to impact cloud-activating properties by altering aqueous-phase H+ concentrations and water activity but is currently overlooked in most atmospheric aerosol models.
