Monte Carlo simulation was used to study the crystal to amorphous tran
sition of ice Ih compressed at low temperatures. By analyzing the time
variation of the pair distribution functions derived from the molecul
ar arrangement obtained from the simulation, relaxation phenomena occu
rring in the course of the transition were investigated. The dominance
of proton movement due to molecular rotation was apparent. (C) 1998 E
