Abstract
Relaxation processes for electrons in alkali metal‐ammonia solutions are calculated to proceed via hyperfine interaction with nitrogen 14 nuclei in dilute solutions (M) and via spin‐orbit interactions in concentrated solutions. Dipolar and exchange interactions are estimated to make only a small contribution to the observed relaxation times. Comparison of the mean square width due to the hyperfine interaction as obtained from relaxation time data and the observed N14 Knight shift allows a construction of an effective wave function for the electron in dilute solutions. In more concentrated solutions (0.60M) relaxation results from fluctuations in the electric potential at an unpaired electron with a correlation time of the order of 10—14 sec. Effects due to the substitution of D for H and Na for K are examined.Keywords
