Molecules are made up of groups of atoms. Describing the structure of an atom, an atom is also sub-divided into smaller units. Protons, electrons, and neutrons are sub-particles of an atom. The protons and neutrons are contained inside the nucleus of the atom and electrons revolve around th...

This raises the question: if collisions of atoms and molecules with semiconductors could produce time-varying electric fields oscillating at similar frequencies, would they not also excite VB electrons to the CB and might this not provide important new avenues of research with the promise of new ...
The OH group is very important because it forms hydrogen bonds with other electronegative atoms. This low-energy bond is easy to form and easy to break and can stabilize biological structures. Molecules can interact with each other through ion–ion interactions, described by Coulomb’s law, ...
Another kind of evidence as to the nature of the action between the molecules is furnished by an experiment made by Dr Joule. Of two vessels, one was exhausted and the other filled with a gas at a pressure of 20 atmospheres ; and both were placed side by side in a vessel of water, ...
Atoms and molecules whose valence electrons can absorb several photons fall in the multiphoton ionization regime class when the Keldysh parameter γ ≫ 1 (γ = (Ip/2Up)1/2, where Up is the laser field’s ponderomotive potential and Ip is the ionization potential). Those systems ...

Motivated by the recent experiment on bosonic mixtures of atoms and molecules, we investigate pairing superfluid–insulator (SI) transition for bosonic mixtures of atoms and molecules in a one-dimensional optical lattice, which is described by an extended Bose–Hubbard model with atom–molecule conserv...
1.由文中“Radiation (辐射) from the Sun continuously breaks two-atom oxygen molecules (分子) into single atoms (原子). Some of these link up with ordinary oxygen (氧) molecules and form ozone.”可知答案。 2.由文中“Without the ozone cover, life on Earth would be literally sunburned to ...
It is an open question, however, whether there exists alternative non-resonant techniques for controlling DDIs that would be robust to broad spectral lineshapes of atoms or molecules with possible room temperature applications. Here we present work related to this new avenue of research. In this ...
