Scattering of High Velocity Neutral Particles. X. He–N2; A–N2. The N2–N2 Interaction
The Journal of Chemical Physics, 1957Total collision cross sections have been measured for helium atoms with energies between 500 and 2100 ev, and for argon atoms with the same energies, scattered in room temperature nitrogen. The results have been analyzed to obtain the average potential between a helium atom and a nitrogen molecule, 〈V(r)〉Av=1.19×10−10/r7.06 ergs,for r between 1.79 A ...

Quantized sequential decay series of metastable N2 cluster ions (N2)+* → (N2)-1+* → … → N2+
Chemical Physics Letters, 1988Abstract The first experimental observation of sequential decay of metastable molecular cluster ions is reported. N 2 cluster ions are produced by electron impact ionization of a supersonic N 2 cluster beam and analyzed by a double-focusing sector field mass spectrometer (reversed geometry).

Vapour-liquid equilibrium data for the systems C2H6 + N2, C2H4 + N2, C3H8 + N2, and C3H6 + N2
Fluid Phase Equilibria, 1977Abstract High pressure vapour-liquid equilibrium data for the C 2 H 6 + N 2 , C 2 H 4 + N 2 , C 3 H 8 + N 2 , and C 3 H 6 + N 2 systems are presented. The data are obtained isothermally in the range from 200 K to 290 K. For each point of data, temperature, pressure and liquid and vapour phase mole fractions are measured.

Linear and centrosymmetric N2⋯Ar+⋯N2
The Journal of Chemical Physics, 2000A high resolution infrared absorption spectrum of the ionic complex N2⋯Ar+⋯N2 has been observed by tunable diode laser spectroscopy through a supersonic planar plasma. Seventy-six rovibrational transitions were measured involving excitation of the antisymmetric NN (ν3) stretching fundamental. The band origin is at 2288.7272(2) cm−1 and the ground state

Propagation of sound in vibrationally excited N2/He, N2/H2, N2/CH4, and N2/H2O mixtures
The Journal of the Acoustical Society of America, 1988Previous measurements of resonant reverberation of sound in N2/H2 mixtures in a closed tube have shown an amplification of the sound following the rapid excitation of the gas by an electric discharge [F. D. Shields, J. Acoust. Soc. Am. 81, 87–92 (1987)]. These measurements have been extended in this article to include N2/He, N2/CH4, and N2/H2O mixtures.

The N2–N2 potential energy surface
Chemical Physics Letters, 1997Abstract Extensive ab initio calculations of the N 2 –N 2 interaction energy have been performed to define its anisotropic behavior with respect to molecular orientation. Additional calibration calculations with larger basis sets have been used to improve the theoretical energies at small separation distances and have been combined with experimental

Rotational spectrum of the N2··CO complex: ortho-N2 and para-N2
Chemical Physics Letters, 1999Abstract Pure rotational spectra of 14 N 2 ··CO, 15 N 14 N ··CO, and 15 N 2 ··CO have been observed using a Fourier transform microwave spectrometer. Two sets of transitions with J=2←1, 3←2, and 4←3 were observed for 14 N 2 ··CO and 15 N 2 ··CO; transitions with smaller ...

The impact of the report by Allen and Senoff in 1965 on the serendipitous discovery of the first complex with coordinated dinitrogen, [Ru(NH3)5N2](2+), is discussed in the context of what was known beforehand and the impact this work had on coordination chemistry.

The mechanism of N2(B3Πg) deactivation by N2
Chemical Physics Letters, 1988Abstract A study of the mechanism for N 2 (B 3 Π g ) deactivation by N 2 has been carried out using chemiluminescence in the reaction N( 4 S) + N( 4 S)(+M) → N 2 (B 3 Π g , ν′ → N 2 (A 3 Σ u + , ν″) + hv . Different N 2 isotopes were used as excited and third-body molecules.

The Journal of Chemical Physics, 1971
Apparent cross sections for the reactions N2++N2→N++N+N2, N2++N2→N3++N, have been measured for laboratory kinetic energies E of N2+ between 1 and 45 eV. The primary ions are produced by electron bombardment and mass analyzed prior to reaction. The bombarding electron energy is varied from 19 to 90 eV, and the effects of excited, long-lived states of N2+
