A neutral-neutral reaction is a chemical reaction that occurs in collisions between atomic or molecular species that carry no electrical charge. Because of the extremely low gas densities that characterize even the densest regions of the ▶ interstellar medium, it is only necessary in this environment to consider bimolecular reactions that occur in ...

Abstract Since the rate coefficients for exoenergetic ion-neutral metatheses are of the order of 10−9 cm3 sec−1, they dominate in controlling the positive ion composition of the ionosphere. Under a reasonable set of assumptions, an equation is derived relating the degree of nitrogen dissociation to the ionic composition. From this relationship, it is

Neutral-neutral reactions for the formation of C3O and C3S
Astrophysics and Space Science, 2014We investigate, neutral-neutral radiative association reactions (C2+CO) and (C2+CS) for the formation of C3O and C3S respectively by DFT. Both the reactions are spin allowed and found to be exothermic and barrierless in nature. The product of these reactions are perfectly linear and the calculated rotational transitions are in good agreement with ...

AbstractA general survey of the reaction of neutral red upon a selected series of living animal organisms is made, and the rationale indicates that neutral red is an indicator of proteolytic enzyme action, whether this be intra‐ or extracellular. Cellular hydrolytic and cellular synthetic systems are thus manifested.

Reactions of Ar+ with various neutrals
The Journal of Chemical Physics, 1981Rakshit and Warneck’s1 recent results for the reactions of Ar+ in the 2P1/2 and 2P3/2 states with various neutrals are commented upon. It is shown that the different rate coefficients for the two argon states reflect the effects in the drift tube used in their research. (AIP)

Experimental studies of ion-neutral reactions are often carried out with specific applications in mind, for instance atmospheric or laser plasmas. Well-developed experimental methods are available in the form of flow tubes, ion-cyclotron resonance methods, ion drift tubes, and ion beam techniques, all of which have been employed extensively.

Photo-Fenton Reaction at Near Neutral pH
Environmental Science & Technology, 2009The photo-Fenton reaction, oxidation of photoproduced ferrous iron by hydrogen peroxide, produces reactive oxidants that may be important to degradation of biologically and chemically recalcitrant organic compounds in surface waters at circum-neutral pH. Sufficient Fe(II) for the photo-Fenton reaction was produced in situ at two field sites (pH 6.1-7.1)

Reactions of Neutral Vanadium Oxide Clusters with Methanol
The Journal of Physical Chemistry A, 2009Reactions of neutral vanadium oxide clusters with methanol and ethanol in a fast-flow reactor are investigated by time-of-flight mass spectrometry. Single-photon ionization through soft X-ray (46.9 nm, 26.5 eV) and vacuum ultraviolet (VUV, 118 nm, 10.5 eV) lasers is employed to detect both neutral cluster distributions and reaction products.

Positional Effects in the Neprilysin (Neutral Endopeptidase) Reaction
Archives of Biochemistry and Biophysics, 1994Neprilysin is a peptidase which has a specificity directed toward cleavage on the amino side of hydrophobic residues. In addition an active site arginine on the enzyme can interact with the C-terminal carboxylate of a substrate. The importance of the position of the hydrophobic residue relative to the C-terminus of the substrate has been investigated ...

Experimental Measurements of the Rate Constants for Neutral-Neutral Reactions
1988This paper gives a brief review of experimental methods used to obtain rate data for neutral-neutral reactions involving free radicals. The application of these methods to reactions of two types — radical-molecule and radical-radical reactions — is illustrated by reference to some recent studies in the author’s laboratory.
