Preparation and Proton Magnetic Resonance Studies of Anhydrous Ammonia

This is the authors' abstract. We don't add key points for this paper.

Comparison of high-resolution proton magnetic resonance spectra of anhydrous N14H3 and N15H3 (99.8% N15) leads to the conclusion that the line width in N14H3 is due to quadrupole relaxation. A new method of preparation of anhydrous, sodium-free ammonia is described. The natural abundance of N15H3 in N14H3 is shown to be observable by magnetic resonance technique.
