Energy molecules

On the experimental side, small molecule energy transfer experiments may use molecular beam teclmiques [65. 66 and 67] (see also chapter C3.3 for laser studies). [Pg.1055]

The kinetic theory attempts to describe the individual molecules energies and interactions statistical thermodynamics attempts to fundamentally develop the equation of state from considerations of groupings of molecules. These approaches are complementary in many ways (3,123,124). A weU-referenced text covering molecular thermodynamics is also available (125). [Pg.248]

If we replace the single molecule energy e,- in q by the energy of the complete ensemble of molecules , and sum over the ensemble states, we create the system... [Pg.61]

Here p is the radius of the effective cross-section, (v) is the average velocity of colliding particles, and p is their reduced mass. When rotational relaxation of heavy molecules in a solution of light particles is considered, the above criterion is well satisfied. In the opposite case the situation is quite different. Even if the relaxation is induced by collisions of similar particles (as in a one-component system), the fraction of molecules which remain adiabatically isolated from the heat reservoir is fairly large. For such molecules energy relaxation is much slower than that of angular momentum, i.e. xe/xj > 1. [Pg.26]

Absorption of radiation in the infrared region of the electromagnetic spectrum results in changes in the vibrational energy of molecules. Energy changes are typically 6 x 103 to 42 x 103J mol-1, which corresponds to 250-... [Pg.378]

Therefore, the various stretching and bending vibrations of a bond usually take place at particular quantized frequencies. Thus, in a situation where upon the infrared light having the same frequency is incident on the molecule, energy is absorbed, and the net effect could be observed by an increase in the amplitude of that vibration. In another situation, whereby the molecule reverts from the excited state to the ground state, the absorbed energy is released in the form of heat. [Pg.316]

Photoelectron spectroscopy (PES, a non-mass spectral technique) [87] has proven to be very useful in providing information not only about ionization potentials, but also about the electronic and vibrational structure of atoms and molecules. Energy resolutions reported from PES are in the order of 10-15 meV. The resolution of PES still prevents the observation of rotational transitions, [79] and to overcome these limitations, PES has been further improved. In brief, the principle of zero kinetic energy photoelectron spectroscopy (ZEKE-PES or just ZEKE, also a nonmass spectral technique) [89-91] is based on distinguishing excited ions from ground state ions. [Pg.46]
