Commentaar over activators en spectra:

O. Ivan Lee investigated what he calls the "reversible photosensitivity" of hackmanite from Bancroft (Ontario) and his response to different UV sources as early as 1936. He presented the phenomenon for the 50th Anniversary Celebration Banquet of the New York Mineralogical Club, in November 18, 1936 at the American Museum of Natural History. It seems that it was the first observation and  the first public announcement and  publication (American Mineralogist vol 21) about photochromism (tenebrescence) in mineralogy.

Chemical analyses revealed that the mineral contains certain amount of sulfur as a substitute for chlorine in the crystal structure.The FTIR spectra of hackmanite showed that the samples contain water. The stretching vibration peak of water of crystallization (H2O) occurs at 3 438 cm-1 and the bending peak is at 1 623 cm-1 . Its tenebrescence is caused by ″hole colour centres″ which are contributed to the presence of sulfur (S22-)) and to some negatively charged chlorine atoms being missing in the crystal structure of hackmanite. (source:

Crystals of Hackmanite of Koksha Valley in Afghanistan are usually found in a matrix constituted by non fluorescing Winchite and/or marble.

Synthetic sodalites containing sulfur and showing considerable photochromic activity have been investigated by ESR. The center responsible for the color has been shown to be an electron trapped at a chlorine vacancy. The origin of the electron which is reversibly transferred during the processes of coloration and bleaching is believed to be the ion S2−. (see  William G. Hodgson, Jacob S. Brinen, and Emil F. Williams, Electron Spin Resonance Investigation of Photochromic Sodalites, The Journal of Chemical Physics 47, 3719 , 1967)
