摘要: Abstract The absorption spectra of the F and M centers in RbF, RbCl, RbBr CsI have been investigated as a function pressure. In addition to bands, No 3 band some other unidentified bands observed. These experiments were conducted at room temperature with both electrolytically additively colored crystals. Frequency shifts observed under pressures up 10,000 atm for RbCl 50,000 RbF CsI. phase transition appears 33,000 atm. pressure dependence frequency shift rubidium halides is similar that potassium halides.
