On the absorption spectra of alkali metal-amine solutions

K. Bar-Eli, G. Gabor

Research output: Contribution to journalArticlepeer-review


We have investigated very carefully the temperature dependence, solvent dependence, and decay rates of the spectra of alkali metals in solutions in methylamine and ethylamine. Results confirm earlier assumptions that the M band is associated with the negative metal ion. The decay rates of these solutions confirm the equilibrium between the metal anions and the solvated electrons. This equilibrium is shifted toward the metal negative ions on cooling. The existence of a new, hitherto unreported, absorption band at 440 nm in solutions of lithium is reported.
