The polyamorphism of triphenyl phosphite has been investigated from a
low-frequency Raman-scattering study. Interesting features about glaci
ation processes have been revealed from a study of the boson peak and
an analysis of the Raman susceptibility in the glacial and crystalline
states. The very close correspondence between the phonon peaks observ
ed in the crystal and the Raman spectrum of the glacial state, as well
as some contradictions about the fragility of the glacial state, if i
t is considered as amorphous, lead us to favor the description of the
glacial state in terms of nanocrystallized domains. [S0163-1829(98)019
