Active Nitrogen by A. Nelson Wright

By A. Nelson Wright

Actual Chemistry, a sequence of Monographs: energetic Nitrogen provides the equipment during which energetic nitrogen will be produced. This ebook consists of 5 chapters that overview the power content material, molecular spectrum, and the emission of energetic nitrogen. many of the issues coated within the e-book are the precis of light-emitting structures of lively nitrogen; research of Long-Lived Lewis-Rayleigh Afterglow conception and Ionic concept of Mitra; reactions by way of precipitated mild emission; and features of homogeneous recombination. different chapters care for the research of metastable molecule theories and the mechanisms for reactions of energetic nitrogen regarding direct N(4S) assault. The dialogue then shifts to the speed constants for reactions precipitated by means of direct N(4S) assault. The review of the Short-Lived lively Afterglow thought is gifted. the ultimate bankruptcy is dedicated to the exam of emission from molecular species with digital strength degrees lower than 9.76 eV. The e-book delivers precious info to physicists, scholars, and researchers.

1 torr. In these, bands from υ' = 3, 4 were of greater intensity than in the discharge itself. Second positive bands have also been reported in the short-duration "blue" and "red" afterglows of Bryan, Holt, and Oldenberg mentioned earlier (224). Here, emission from higher vibrational levels was more extensive and the rotational temperatures were higher, than in the bands emitted by the discharge. A plot of (intensity) -1 / 2 against time of decay was linear for the "blue," but not for the "red" afterglow.

The first systematic studies of this system, published in 1924, indicated a sharp cutoff of the rotational levels in the fourth vibrational level (354-356). Kaplan subsequently pointed out that no bands were observed in the second positive system with v' > 4 (205), and Herzberg suggested that the obser* For example, a 100 kilowatt unit, with emission at 3371A (Model C102) may be ob­ tained from the Avco Everett Research Laboratory, Everett, Massachusetts. ///. 76 eV 35 vations could be attributed to a predissociation in the C 3 /7 M state at v' > 4 (357).

Their intensity was markedly increased at low temperatures, and especially at the temperature of liquid air. They also appear to be emitted in the "light of the night sky" (346, 419), from the aurora (303, 346), from nitrogen that has been mildly excited with an "ozonizer-type" discharge (91,307) or with a Tesla coil (91), from nitrogen excited by 50 keV electrons (366b), and from discharges through argon-oxygen-nitrogen mixtures (348). 5 kV dc discharge through nitrogen at liquid air temperature, and pressures of 1 to 30 torr (314).
