Translation of "Proton transfer" in German

The dominant destruction pathway in dense interstellar clouds is by proton transfer with a neutral collision partner.

A temperature-controlled proton transfer in the anthocyanidin structure triggers the change in colour.

The latter releases the polymerization-triggering free radicals through electron or proton transfer or direct hydrogen abstraction.

This coinitiator releases the polymerization-initiating radicals as a result of electron transfer or proton transfer or of direct hydrogen abstraction.

This is caused by an intramolecular proton transfer which proceeds within only 160 fs and is initiated by UV excitation.

So they won valuable insights how the proton transfer can take place at a physiological pH values.

Here, the proton transfer is driven by the salt's lattice energy which is released chloride, as the driving force for completion.

This may contribute to effective proton transfer and also to a particularly stable base.

Eigen also published his central thesis on proton transfer in water in Angewandte Chemie in 1964.

However, a proton transfer still can take place, which can potentially change the total nuclear spin of the two molecules depending on the nuclear spins of the protons.

German Patent Application DE 198 17 374 A1 describes mixtures of sulfonated aryl polymer (PEEK and PSU) and polybenzimidazole (PBI) which are covalently cross-linked due to the proton transfer from the sulfonated aryl polymer to the PBI (e.g., PEEK-SO 2 —O—H—N-PBI).

On the other hand, polymers substituted by primary or secondary amino groups cannot be prepared by reaction with primary or secondary amines, since the latter simply result in termination of living polymers by proton transfer.

The international group of researchers combined for the first time nuclear magnetic resonance experiments (NMR) with neutron protein crystallography in order to investigate the effect of pH and divalent cations during proton transfer in the human carbonic anhydrase II.

With ultrafast spectroscopy it has been shown that the elementary steps in aqueous proton transfer occur on femtosecond to picosecond time scales (1 femtosecond = 10-15 s = 1 millionth of a billionth of a second).

Type II photoinitiators (Norrish type II) for radical polymerization undergo a bimolecular reaction on irradiation wherein the photoinitiator reacts in the excited state with a second molecule, the coinitiator, and forms the polymerization-inducing radicals by electron or proton transfer or direct hydrogen abstraction.

DE-A-198 17 374 discloses blends of sulfonated aryl polymer (PEEK and PSU) and polybenzimidazole PBI which have covalent crosslinking by means of proton transfer from the sulfonated aryl polymer to PBI (e.g.

The molar ratio between the starting compounds anthocyanidin and fatty acid and/or gallate, including the derivatives and mixtures thereof, crucially controls the proton transfer in the natural dye and hence the thermochromic behaviour.

Type II photoinitiators (Norrish type II) for free-radical polymerization undergo a bimolecular reaction on irradiation wherein the photoinitiator reacts in the excited state with a second molecule, the coinitiator, and forms the polymerization-inducing free radicals by electron or proton transfer or direct hydrogen abstraction.
