Abstract
The infrared spectroscopy and dynamics of HCl hydrogen bonded clusters in solid parahydrogen were investigated using high-resolution FTIR spectroscopic methods. This paper will focus on the HCl dimer species. Transitions have been observed and assigned to both the ``donor'' and ``acceptor'' HCl stretching modes of $(HCl)_{2}$. The spectroscopy indicates that end-over-end rotation of the dimer is quenched in solid parahydrogen, but that low frequency motions involving K rotation and possibly tunneling are still occurring. More detailed analysis is underway and will be presented at the meeting.
