High resolution Fourier transform infrared emission spectra of MgH and MgD have been recorded. The molecules were generated in an emission source that combines an electrical discharge with a high temperature furnace. Several vibration-rotation bands were observed for all six isotopomers in the X (2)Sigma(+) ground electronic state: v=1-->0 to 4-->3 for (24)MgH, v=1-->0 to 3-->2 for (25)MgH and (26)MgH, v=1-->0 to 5-->4 for (24)MgD, v=1-->0 to 4-->3 for (25)MgD and (26)MgD. The new data were…

Terahertz spectroscopy of 25MgH (X2Σ+) and (67)ZnH (X2Σ+): bonding in simple metal hydrides.

Results suggest significant covalent character in both MgH and ZnH, in contrast to their fluoride analogs, and compare that the unpaired electron resides in a σ molecular orbital that has significant s contributions from both the metal and the hydrogen atoms.
