Abstract:In preparation for our FTMW study of the complex between hydrogen and silver bromide, H$_{2}$-AgBr, we have investigated the microwave spectra of our source of bromine, dibromodifluoromethane, CBr$_2$F$_{2}$. Previous sources of bromine to produce AgBr proved either too damaging to the instrumentation in the long term (Br$_{2}$), or did not produce enough AgBr to be useful (CHBr$_{3}$). In addition, silver bromide, originally studied by Hoeft, Lovas, Tiemann, and Torring in 1971,\footnote{J. Hoeft, F. J. Lovas, E. Tiemann, T. Torring, Z. Naturforsch. 25a, 35 (1970).} and remeasured by Evans and Gerry in 2000,\footnote{C. J. Evans, M. C. L. Gerry, J. Chem. Phys. 112, 1321 (2000).} was remeasured once more. We plan to produce H$_{2}$-AgBr, using laser ablation of a silver rod within a supersonic expansion of an argon carrier gas containing H$_{2}$ and CBr$_{2}$F$_{2}$. This is part of our ongoing study of hydrogen complexed with metal halides which include H$_{2}$-CuF,\footnote{D. J. Frohman, G. S. Grubbs II, Z. Yu, S. E. Novick, Inorg. Chem. 52, 816 (2013).} H$_{2}$-AgCl,\footnote{G. S. Grubbs II, D. A. Obenchain, H. M. Pickett, S. E. Novick, J. Chem. Phys. 141, 114306 (2014).} and H$_{2}$-AuCl.\footnote{D. A. Obenchain, G. S. Grubbs II, H. M. Pickett, S. E. Novick, J. Chem. Phys. 146, 204302 (2017).} These molecules are “models” of the molecular hydrogen storage in the cavities of metal organic frameworks (MOFs).
