  pages={45 - 46}
Ammoniated electrons exist in solutions of potassium amide in liquid ammonia which have reached thermodynamic equilibrium with hydrogen gas. By determining electron concentrations by electron spin resonance, an equilibrium constant of 105 at room temperature has been obtained.

Electron Paramagnetic Resonance Study of Solutions of Europium in Liquid Ammonia
The electron spin resonance spectrum of a solution of Eu in liquid ammonia consists of a single line characteristic of the solvated electron and a complex hyperfine pattern which is shown to arise
Living Polymers and Mechanisms of Anionic Polymerization
Following a short introduction and a brief discussion of thermodynamics of propagation, the kinetics and mechanisms of anionic polymerization are reviewed. The systems involving living polymers, a

Radiocarbon and Soil Evidence of Former Forest in the Southern Canadian Tundra
Radiocarbon dating of charcoal on podzols along a transect reaching 280 kilometers north of the present tree line from Ennadai Lake indicates that former forests were burnt about 3500 years ago and


Heats of Solution of Alkali Metals in Liquid Ammonia at 25
Heats of solution in ammonia at 25° have been measured for Li, Na, and K at concentrations down to 0.005 M, and for Na in the presence of NaI. Dilution is endothermic, and the heat of dilution is
Interpreting liquid ammonia chemistry with thermodynamics
It is the purpose of this article to show that it is possible to systematize the chemistry of liquid ammonia with thermodynamic data.
Paramagnetic Resonance Absorption in Solutions of K and Na in Liquid NH3
Paramagnetic resonance absorption in solutions of K and Na in liquid NH3 has been investigated. The resonance has been studied at a frequency of approximately 7.0·106 cycle sec−1 and a magnetic field
These results are consistent with the known exothermicity of the reaction as written above. Thermochemical data of L
