In this article, a high resolution solar spectrum in the range 200 to 220 nm has been recorded with an echelle spectrograph launched in, a sun-pointing Skylark rocket.Abstract:
A high resolution solar spectrum in the range 200 to 220 nm has been recorded with an echelle spectrograph launched in, a sun-pointing Skylark rocket. The data have been reduced and are presented as intensity-wavelength plots together with a wavelength list and proposed identifications. A broad absorption feature at 212.4 nm is assigned to a single source and an intensity analysis confirms this to be the non-resonance Sii line at 212.412 nm. The discontinuity in the continuum intensity near 208.7 nm is revealed with high resolution for the first time and is assigned to the photoionization edge of A11. An analysis shows that its intensity drop and wavelength position can only be explained by adjustments to the solar model in the region 0.001read more

Stratospheric Ozone: An Introduction to Its Study
TL;DR: In this paper, an analysis is made of the various reactions in which ozone and atomic oxygen are involved in the stratosphere, and the predicted effects of these reactions are determined based on the vertical distribution of the H2O, CH4, and H2 dissociation by reaction of these molecules with electronically excited oxygen atom O(¹D).

Vertical distribution of NH3 in the upper Jovian atmosphere from IUE observations
M. Combes,Th. Encrenaz,Régis Courtin,John Caldwell,Tobias Owen,V. Moore,K.H. Fricke,P. S. Butterworth +7 more
TL;DR: The first unambiguous identification of ammonia in the upper atmosphere of Jupiter has been obtained from the observation of individual NH 3 bands in an IUE high resolution spectrum in the 2100-2400 A spectral range as mentioned in this paper.

Some Problems Relating to Solar Line Identification
TL;DR: In this article, a review is given of some of the problems of classification and intensity analysis involving unidentified or recently identified lines in the ultraviolet solar spectrum, and attention is drawn to the present position regarding two and three electron spectra in the soft X-ray region, and forbidden transitions within the ground configurations at longer wavelengths.

TL;DR: In this article, the authors compare the interpretation of the solar UV continuum between 3000 A and 1680 A with theoretical computations, in which a significant difference between the observations and the computations still exists.

Experimental Transition Probabilities for Neon i
TL;DR: Transition probabilities of visible and near-IR neon lines, using gas-driven shock tube spectroscopy, were obtained in this paper, where the transition probabilities were shown as a function of the number of neon lines.
