Infrared and Raman spectra of polycrystalline samples of nitric oxide N2O2, at temperatures between 18 and 80 K have been recorded, and several new low frequency peaks observed. The Raman spectrum of the liquid at 115 K has also been obtained, in an

Results of incoherent quasielastic neutron scattering experiments on quinuclidine, C7Hl3N, in its plastic phase (room temperature) are presented. The observed quasielastic spectra are compared to several models for the rotational motion of the molecu

Laboratory kinetic energy distributions of N + and O + fragments arising from 5 keV collision-induced dissociation of parent NO + ions with helium, are reported. These observations allow us to determine both the amount of translational energy convert

In plastic crystals (“rotary phases”) there is a dynamic disorder of the orientations of the molecules. But reorientations can exist without disorder (jumps between equivalent orientations, e.g. benzene), and on the other hand frozen disorder can

An effective model-potential approach is devised in order to determine potential energy surfaces and interactions relevant to the study of non-adiabatic proton+molecule collisions. The procedure is illustrated on the low-lying 3A″ states of the H++

Phonon dispersion curves in the principal symmetry directions of trigonal selenium single crystals have been measured by neutron inelastic scattering, using a three-axis spectrometer. The acoustic modes and the three lowest-lying optical modes ( q =

The dielectric behavior of moist desoxyribonucleic acid fibers at low frequencies has been studied, and is explained phenomenologically. This behavior is nonlinear with respect to the thickness of the sample and to the applied voltage. The experiment
