Discharge in nitrogen

Figure 6. Glow discharge in nitrogen Pressure = 0.3 mm Hg nickel cathode ions are sampled from the cathode % yield refers to % total ions observed. At very low discharge currents the distinct glow in front of the cathode disappears, and a continuous glow corona) is obtained throughout the discharge tube...

A group of transitions with the same value of A.v is referred to as a sequence. Because of the population requirements long sequences are observed mostly in emission. For example, sequences of five or six members are observed in the C37/ - S7/ band system of N2 in emission in the visible and near-ultraviolet from a low-pressure discharge in nitrogen gas. The vibration wavenumber coe is high (2047.18 cm-1) in the C state and equilibrium population of the vibrational levels is not achieved before emission.

Relation (3-57) permits us to find tire exact value of the factor 8 — 1 m/M. In molecular gases, however, this factor is usually considered a semi-empirical one. For example, (5 3 10 in typical conditions of non-eqnilibrinm discharges in nitrogen. Taking into...

A further interesting aspect of the metastable atom technique is the production of N2(A S ) excited molecules in the absence of the N atoms, which are invariably present in the products of an ordinary microwave of r.f. discharge in nitrogen. Energy transfer processes involving N2(A S 5 ) molecules have been characterized in this way. ... 

A reaction in N2 similar to (51) and (52) has been proposed by Lund and Oskam from mass spectrometric studies of the time dependences of the ionic species present in the afterglows of pulsed radiofrequency discharges in nitrogen. Specifically, they suggest... 

Discharges in nitrogen have received considerable attention. The ions of nitrogen, N , were observed in the early discharge experiments of Thompson (n = 0 to 3) and Luhr (n = 0 to 4). The drift space they employed probably assisted in the formation of the triatomic and tetratomic species.
