The vibration rotation energy of an electronic state of a diatomic molecule is commonly represented by [E.sub.vJ] = [E.sub.v] + [lambda][B.sub.v] + [[lambda].sup.2][D.sub.v] + [[lambda].sup.3][H.sub.v] + [[lambda].sup.4][L.sub.v] + [[lambda].sup.5][M.sub.v] ..., where [lambda] = J(J + 1), v and J are, respectively, the vibrational and rotational quantum numbers, [E.sub.v] is the pure vibrational energy, [B.sub.v] the rotational constant, and [D.sub.v], [H.sub.v], [L.sub.v] + ...
Although CO is suggested to be involved in many pathological conditions, the relevant research is only at an early stage, with many diseases yet to be explored towards their response to this interesting diatomic molecule. Since only few studies are focusing on the role of CO, along with biliverdin, bilirubin, iron, and ferritin, in carcinogenesis [8], this review aims to elucidate the role of this gasotransmitter in the form of CORMs, in tumorigenesis, along with angiogenesis and metastatic progression.
In the vapor phase it is a diatomic molecule. It has been detected in stellar objects and it has been described as the most common oxide of silicon in the universe.
The factor of five in the numerator of Equation 1 is the number of kinetic degrees of freedom for a diatomic molecule at room temperature; in addition to the three translational degrees of freedom, diatomic molecules also have two rotational degrees of freedom.
The rotational diatomic relaxation in dense fluids determines the basic properties of the far-infrared absorption bands, which, depending on the diatomic molecule and the thermodynamic conditions of the solution, can present a fine rotational structure associated with the R-branch of the gas phase spectra.
In the classical regime the sum of probability densities |ps1|2+|ps2|2 of the detached-electron from individual atoms is equal to the probability density |ps|2from the diatomic molecule. The classical limit calculations for interatomic distance between two coherent sources depend on detached-electron energy as well as photon energy.
So two atoms of the mystery element frequently bond together to form a more stable diatomic molecule (particle containing two atoms).
This condition contrasts with common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths.The word "excimer" is a contraction of "excited dimer," a dimer being a diatomic molecule of an inert gas whose halogen atoms are bound in the highly charged (excited) state, temporary and unstably.
Here we consider the Morse interaction [2,12] which represents an approximation to vibrational motion of a diatomic molecule.
[H.sub.2] is larger because it's a diatomic molecule. More important, then, is the fact that no other gases fragment during ionization into any ion species that have a mass of 4, while H+ and [H.sub.2]+ ions are commonly produced by fragmentation of water vapor and hydrocarbons.
