Optical absorption spectra obtained on glasses quenched from sodium silicate melts show Mn 3+ to be the dominant species for melts heated in air and Mn 2+ to be the dominant species for melts heated at Po 2 = 10 -17 bar. The absorption spectrum of Mn 3+ consists of an intense band at 20,000cm -1 with a 15,000cm -1 satellite possibly arising from the Jahn-Teller effect. The independence of the spectrum from melt composition and the high band intensity is offered as evidence for a distinct Mn 3+ complex in the melt. The spectrum of Mn 2+ is weak and many expected bands are not observed. A two-band luminescence spectrum from Mn 2+ has been tentatively interpreted as due to Mn 2+ in interstitial sites in the network and Mn 2+ coordinated by non-bridging oxygens.
