Matrix isolation of Mg2 and Mgn molecules in neon, argon, and nitrogen hosts
Knight, L. B.; Ebener, M. A. Matrix isolation of Mg2 and Mgn molecules in neon, argon, and nitrogen hosts. J. Mol. Spectrosc. 1976, 61, 412-422.
The Mg2 and Mgn molecules have been formed and studied in neon, argon, and nitrogen matrices at approximately 4-° and 12 K. Bands observed between 2000 and 3500 Ã… have been investigated as a function of gradual changes in trapping conditions and assigned to various stages of magnesium atom polymerization. The A1Î£u+ -† X1Î£g+ system of Mg2 relative to the gas exhibits a pronounced red shift which increases with the polarizability of the matrix host. A band at 2653 Ã… in argon was observed which can be tentatively assigned to another Mg2 system.
