light hydrogen

The light hydrogen tends to be drawn off first, leaving the heavy water behind.

Thought it had to be all light hydrogen.

Most of a star's mass consists of light hydrogen and helium.

The nuclear magnetic resonance frequency of deuterium is significantly different from common light hydrogen.

Hydrogen-1, also known as protium or "light hydrogen" is the main component of natural hydrogen.

In October a further pair of patent applications detailed ways of squeezing more power from lighter hydrogen fuel cells.

Heavy hydrogen is very useful for slowing (moderating) neutrons, and absorbs far fewer than light hydrogen.

The most abundant isotope, hydrogen-1, protium, or light hydrogen, contains no neutrons and is just a proton and an electron.

They could allow, in theory if not in practice, the fusion of light hydrogen atoms with heavier atoms such as lithium or boron.

Deuterium ("heavy hydrogen") already has the extra neutron that light hydrogen would absorb, reducing the tendency to capture neutrons.

As clouds rise up the side of mountains, water droplets containing the heavier deuterium fall first, and droplets containing the lighter hydrogen later.

High abundance of water vapor in the atmosphere allowed photodissociation to occur, with lighter hydrogen gas escaping to space and oxygen reacting with surface rocks.

The wavelengths of all deuterium spectroscopic lines are shorter than the corresponding lines of light hydrogen, by a factor of 1.000272.

It exists whenever there is water with light hydrogen (protium, H) and deuterium (D orH) in the mix.

Proton NMR is also important because the light hydrogen nucleus is not easily detected by X-ray crystallography.

When solutions of sulfide solutions containing dispersed CdS particles are irradiated with light hydrogen gas is generated:

A test series in 1954 demonstrated highly favourable results from much lighter hydrogen bomb designs, and suddenly the ICBM appeared to be a very practical possibility.

He gives me a blushing peek through the curtain at nonconcentric electron shells and light hydrogen atoms where electron and proton are separated by infinity.

Since the overwhelming share of the water in Earth's oceans is made with the light hydrogen atom, astronomers calculated that comets could have accounted for only about 10% of what's there.

However, light hydrogen is also fairly effective at absorbing neutrons, and there will be too few left over to react with the small amount of U in natural uranium, preventing criticality.

Similarly, sound travels about 1.41 times faster in light hydrogen (protium) gas than in heavy hydrogen (deuterium) gas, since deuterium has similar properties but twice the density.

In PWRs the coolant water is used as a moderator by letting the neutrons undergo multiple collisions with light hydrogen atoms in the water, losing speed in the process.

Infrared spectroscopy also easily differentiates many deuterated compounds, due to the large difference in IR absorption frequency seen in the vibration of a chemical bond containing deuterium, versus light hydrogen.

Engineers have been unable to determine the root cause of the cracks, but they suspect it is due to the metal flexing from the extreme cold of the shuttle's liquid oxygen and light hydrogen propellants.

Light hydrogen isotopes are more likely to be found in the air and escape into space than heavier ones; the smaller the oceans, the more their waters will have slightly lower concentrations of light isotopes.
