Electronic Water Dissocation Via Radiolysis

In summary, the conversation discusses using high frequency radiation to dissociate water molecules. The atomic distances and corresponding frequencies of the water dimer are mentioned, as well as the absorption of water in the ultraviolet range. The possibility of using a lithium niobate piezoelectric crystal to eject high-energy electrons towards lead shielding is also proposed. The frequency of the resulting X-ray radiation is dependent on the voltage and frequency used to emit the electrons, and the speaker is seeking to calculate this frequency in order to achieve the desired results.

Hi, all.

Ok, sort of a weird question, and I'm not even sure if I'm asking it correctly, but here goes:

First, some background:
======================================
======================================
According to:
Hydrogen Bonding and Orbital Models
In ambient atmosphere the O—O in the water dimer is 2.985 angstrom (calculated by JMW); the short O—H bond is 0.948 angstrom and the long bond is 2.037 angstrom.

That's .2985 nm, .0948 nm and .2037 nm.

2.037 angstrom corresponds to a frequency of 1.4717e+18 Hz or 1.4717 ExaHertz. X-ray range.

2.985 angstrom corresponds to a frequency of 1.0043e+18 Hz or 1.0043 ExaHertz. X-ray range.

0.948 angstrom corresponds to a frequency of 3.1624e+18 Hz or 3.1624 ExaHertz. X-ray range.

Water Radiolysis - Dissociating Water with Radio Waves
"Guenther and Holzapfel irradiated water with X-rays in contact with a large free volume in a vacuum system and found large continuing yields of hydrogen gas."

According to:
https://en.wikipedia.org/wiki/Electr...ption_by_water
Water has its highest absorption at 65 to 70 nm, which is 4.2827e+15 to 4.4087e+15 Hz. That's ultraviolet range. But that'd just cause the water to heat up, I think.

So, if we hit the water with:
1.0043 ExaHertz
1.4717 ExaHertz
3.1624 ExaHertz
that should excite all the points of vibration in the molecules (and between the molecules) at their resonant frequencies, forcing the molecules to dissociate.
======================================
======================================

Notwithstanding that it'd be difficult to electronically generate that high a frequency with a tank circuit, I think I've hit upon a solution... use a lithium niobate piezoelectric crystal to eject high-eV electrons.

If we eject a high-eV electron directed toward lead shielding, when that electron impinges upon that lead shielding, it'll give off a photon in the X-ray range, with the frequency of that X-ray photon dependent upon the kinetic energy of the originating electron. The kinetic energy of the originating electron is dependent upon the voltage and frequency used to emit it.

So... how do I calculate the frequency of that resultant X-ray radiation, given only the voltage and frequency used to emit the electron toward the lead shielding, such that I can adjust the input voltage and frequency to the lithium niobate PZ (to adjust the kinetic energy of the emitted electrons), and thus arrive at the three frequencies above?

Then you have a wavelength corresponding to the atomic distance. So what? The energy of the photons at that frequency is significantly above the scale of the electron energies.

Those frequencies do not have a special meaning for water.
 

1. What is electronic water dissociation via radiolysis?

Electronic water dissociation via radiolysis is a process in which water molecules are broken down into smaller components, such as hydrogen and oxygen ions, by the action of high energy radiation. This process can occur naturally in the Earth's atmosphere, but it can also be artificially induced in laboratory settings.

2. What type of radiation is used in electronic water dissociation via radiolysis?

The most commonly used type of radiation for electronic water dissociation via radiolysis is high energy electrons. Other types of radiation, such as gamma rays and X-rays, can also be used but are less efficient at breaking down water molecules.

3. What are the potential applications of electronic water dissociation via radiolysis?

Electronic water dissociation via radiolysis has potential applications in the fields of energy production and environmental remediation. It can be used to produce hydrogen gas, which can be used as a clean and renewable energy source. It can also be used to break down pollutants in water, making it a useful tool for cleaning up contaminated environments.

4. How does electronic water dissociation via radiolysis differ from traditional water electrolysis?

In traditional water electrolysis, an electric current is used to split water molecules into hydrogen and oxygen ions. In electronic water dissociation via radiolysis, high energy radiation is used instead of an electric current. This makes it a more efficient process, as it requires less energy and does not produce any harmful byproducts.

5. What are the potential risks associated with electronic water dissociation via radiolysis?

One potential risk of electronic water dissociation via radiolysis is the production of harmful byproducts, such as free radicals, which can be damaging to living organisms. Another risk is the potential for radioactive contamination if the process is not properly controlled and contained. It is important for scientists to carefully consider and mitigate these risks when using this technology.
