Abstract:

The high resolution work undertaken at Castle with three spectrographs of relatively high dispersion is described and analyzed. Profitable results were obtained from the spectra taken with the JACO 21-foot Wadsworth-mount spectrograph, mainly the highest violet cutoff to date and a very predominant NO2 spectrum in absorption. There is a definite indication that the NO2 exists in a state of excitation above that observed at ordinary room temperature. The observation as a function of time of the formation NO2, which conceivably can be formed in different ways during different intervals of the explosion, would be of great interest.
