摘要：

Using neutron inelastic scattering we have measured some phonons of anomalously low frequency in perdeuteronaphthalene. This supports results obtained by others studying vibronic transitions. These phonons occur near the Brillouin zone boundary and therefore would contribute prenounced peaks in the density of phonon states, at about 10 cm-1 and 30 cm-1. We cannot at present identify the form of molecular motion in these phonons. © 1969.
