摘要：
The Raman scattering of mercury(I) fluoride was investigated over the temperature range from 35 to 500 K. A low-lying peak was found at 23.5 cm -1 over the entire temperature range and is considered to be a transverse acoustic mode frozen to the Gamma point. The Raman spectrum accompanying the low-lying mode indicates the low symmetry reduced from the room-temperature phase (I4/mmm). The distance of the Hg-Hg bonding was evaluated to be 2.55 AA from the classical Badger rule.
