Statistical theory of an adiabatic process
Physical Review E, 1995Within the existing phenomenological theory of an adiabatic process it is implicit that the system is characterized by a temperature at any moment. However, since in this process there is no thermostat, the probability distribution in general would not be canonical.

A detailed numerical model of a Skarstrom-like PSA process is used to investigate the separation performance of an adiabatic and a non-adiabatic process for removal of bulk CO2 impurity from inert He. The complexity of the gas phase adsorbate composition,

Some characteristics of the atmosphere during an adiabatic process
, 2006Some important characteristics of the atmosphere during an adiabatic process are investigated, which include the invariability of atmospheric entropy range and local surface potential temperature, the conservation of the atmospheric mass intervened ...

Coherence-Transfer Processes by Adiabatic Pulses
Journal of Magnetic Resonance, Series A, 1996The effect of adiabatic double-resonance excitation on the indirect spin–spin coupling spectra of a liquid-like spin system is discussed. It is shown in detail how adiabatic excitation affects the coherence-transfer process from one spin species to another (restricted to the case of two spin-12 nuclei), when the indirect Hamiltonian cannot be ...

The Hydrostatic Equation and Adiabatic Processes
2021In addition to obeying the Ideal Gas Law and principles of adiabatic motion, air moves vertically based on the principles described in the hydrostatic equation, which relates height differences in a static atmosphere to the vertical pressure change over those differences.

Radiation Process as an Adiabatic Process
Journal of the Physical Society of Japan, 1981It is shown that Zener's theory of adiabaticity is applicable to find the probability of photon absorption (or emission) by molecules. In contrast to the conventional approach based on Dirac's time dependent perturbation theory, in which the broadening of spectral lines is of secondary importance, the present theory shows that spatial inhomogeneity ...

Cis-trans photoisomerization of a p-styrylstilbene, a one- and twofold adiabatic process
, 1990The mechanism of the Z/E photoisomerization of a p-styrylstilbene has been studied by steady state and time-resolved fluorescence measurements combined with isomerization quantum yield determinations.

Pressure and Adiabatic Processes
2009According to Chap. 5 a quantity, which may meaningfully be termed “pressure,” is required to exist, at least in equilibrium. This variable relies on a process, in which some extensive quantity changes while entropy remains invariant (adiabatic processes). Here a definition of pressure based on the quantum microstate is given.
