Book Description
The 'auroral afterglow' or short-duration afterglow of nitrogen is studied with particular attention to relative intensities in the emission spectrum. It is assumed that in an intense discharge through pure nitrogen, excitation in steps via metastable states occurs. (Author).

Book Description
An attempt is made to explain the 'auroral afterglow' or short-duration afterglow of nitrogen, discovered in 1932 by Kaplan, in terms of well established processes. In this afterglow, N2+ bands are excited together with bands of neutral N2 molecules, which show energies far exceeding the limit evident in the well known long-duration afterglow (Lewis-Rayleigh afterglow). This limit is given by the energy of recombining N atoms, 9.76 eV. (Author).

Book Description
Physical Chemistry, A Series of Monographs: Active Nitrogen presents the methods by which active nitrogen may be produced. This book is composed of five chapters that evaluate the energy content, molecular spectrum, and the emission of active nitrogen. Some of the topics covered in the book are the summary of light-emitting systems of active nitrogen; analysis of Long-Lived Lewis-Rayleigh Afterglow theory and Ionic theory of Mitra; reactions followed by induced light emission; and characteristics of homogeneous recombination. Other chapters deal with the analysis of metastable molecule theories and the mechanisms for reactions of active nitrogen involving direct N(4S) attack. The discussion then shifts to the rate constants for reactions induced by direct N(4S) attack. The evaluation of the Short-Lived Energetic Afterglow theory is presented. The final chapter is devoted to the examination of emission from molecular species with electronic energy levels below 9.76 eV. The book can provide useful information to physicists, students, and researchers.

Book Description
We have studied the products of Ar/N20 microwave discharges to determine their fitness as sources of atomic oxygen in discharge-flow reactors. For N20 feed rates below 10-20 micromol s−1, the discharge converts about 75 percent of the N20 to atomic oxygen, and in addition, produces small quantities of atomic nitrogen, generally less than 10 percent of the 0-atom product. At higher N20 feed rates the 0-atom production efficiency decreases, and some nitric oxide accompanies the 0-atoms out of the discharge.
