Effect of Irradiation on the Intensity Distribution of the Second Positive Nitrogen Bands excited in a Nitrogen Ozonizer

Nature volume 171, pages 86–87 (1953)Cite this article

Abstract

MORE exact measurements have now been made of the changes in the relative intensities of several bands of the second positive system of nitrogen, brought about by irradiation with the 3650–3660 A. group of mercury radiations, using an ozonizer discharge tube excited under conditions yielding the maximum negative Joshi effect when the pressure of the gas is 20 mm. These confirm, in general, the results of preliminary investigations1 and show further that the percentage decreases of intensity are in the following order of bands: In sequences : (1,4) > (0,3) ; (1,3) > (0,2) In progressions : (0,3) > (0,2) > (0,1) ; (1,4) > (1,3). The results show that a change in the relative intensity distribution of the second positive bands of nitrogen is thus brought about, not only in sequences but also in progressions.
