Infrared and Raman Study of Vibrational Relaxation in Liquidslative to internal degrees of freedom of a molecular liquid and is generated by a large variety of intermolecular forces, the dipole-dipole, dipole-induced dipole, dispersion, Pauli repulsion forces and hydrogen bonding. The relaxation due to the centrifugal or Coriolis forces is generally, although

Collision-Induced Vibrational Spectroscopy in Liquidsernary and higher order interactions. The induced dipole is modulated by the vibration and rotation of the colliding molecules and, because of its strong dependence on the intermolecular separation, by their relative translational motion. Thus a variety of pressure-induced spectra are known ranging

Picosecond Vibrational Spectroscopyht pulses in the spectral region extending from the near uv to the infrared. (1,2) These pulses allow direct studies of ultrafast molecular processes with an exceptional time resolution of a fraction of a picosecond. The present chapter discusses applications to the study of vibrational dynamics in

Vibrational Bandshapes in Viscous Liquids and Glassesons associated with the simplicity of the molecular shapes, are only observed in highly fluid states. Any attempt to decrease their fluidity and concomitantly to increase the various associated structural and rotational relaxation times, e.g. by decrease of temperature or increase of pressure, is qu

This offers the advantage of making possible the calculation of a wide range of crystal properties from the same intermolecular potential, such as for instance the crystal structure, the thermodynamic and several dynamical properties.
