How Inert, Perturbing, or Interacting Are Cryogenic Matrices? A Combined Spectroscopic (Infrared, Electronic, and X-ray Absorption) and DFT Investigation of Matrix-Isolated Iron, Cobalt, Nickel, and Zinc Dibromides.

The interactions of FeBr, CoBr, NiBr, and ZnBr with Ne, Ar, Kr, Xe, CH, and N matrices have been investigated using IR, electronic absorption, and X-ray absorption spectroscopies as well as DFT calculations. ZnBr is linear in all of the matrices. NiBr is linear in all but N matrices, where it is severely bent.
