Sentences with phrase «state of the hydrogen molecule»

The researchers also demonstrated microscale MRI images in a micro-reactor using parahydrogen, a state of the hydrogen molecule in which the nuclei are aligned in opposite directions.

Not exact matches

The scientists prepared the molecules so that the temperature — judged by the probability of an atom's nucleus being found in a higher energy state — was greater for the hydrogen nucleus than for the carbon.

Researchers can now study how water behaves when stripped of the hydrogen bonds that normally govern its properties, as well as the molecule's two different «spin» states, which can not be separated when water molecules are en masse.

Seeing hydrogen is critical to studying protonation states of an enzyme and ligand — a molecule that binds to a biological macromolecule — and to analyzing the architecture of hydrogen - bonding networks.

The presence of the sugar molecules jostling the atom have the effect of «observing» it, they argue, forcing the hydrogen to snap into one position, just as measuring the state of any quantum particle will fix it to one set location.

Squeezing hydrogen at extreme pressures changes it into a mix of honeycombed atoms layered with free - floating molecules — an entirely new state of the element and the first new phase found in decades.

The hydration sphere and the hydrogen bonds will have different dimensions in the frozen state and hence would not the configurations of the dissolved or dispersed molecules be different in the frozen state than at normal room temperatures?

In principle, odorant isotopomers provide a possible test of shape vs. vibration mechanisms: replacing, for example, hydrogen with deuterium in an odorant leaves the ground - state conformation of the molecule unaltered while doubling atomic mass and so altering the frequency of all its vibrational modes to a greater or lesser extent [11].
