Energy mechanisms

Many phenomena in solid-state physics can be understood by resort to energy band calculations. Conductivity trends, photoemission spectra, and optical properties can all be understood by examining the quantum states or energy bands of solids. In addition, electronic structure methods can be used to extract a wide variety of properties such as structural energies, mechanical properties and thennodynamic properties. [Pg.113]

MO (STO-3G) calculations on the gas-phase hydration reaction of formaldehyde suggest a concerted process involving two water molecules as a low-energy mechanism for hydration. [Pg.451]

Aldehydes and ketones undergo reversible addition reactions with alcohols. The product of addition of one mole of alcohol to an aldehyde or ketone is referred to as a hemiacetal or hemiketal, respectively. Dehydration followed by addition of a second molecule of alcohol gives an acetal or ketal. This second phase of the process can be catalyzed only by acids, since a necessary step is elimination of hydroxide (as water) from the tetrahedral intermediate. There is no low-energy mechanism for base assistance of this... [Pg.451]

The kinds of substitution mechanisms that may be relevant to super-low concentration elements such as Pa involve intrinsic defects, such as lattice vacancies or interstitials. Vacancy defects can potentially provide a low energy mechanism for heterovalent cation substitution, in that they remove or minimise the need for additional charge balancing substitutions. Formation of a vacancy per se is energetically unfavourable (e.g., Purton et al. 1997), and the trace element must rely instead on the thermal defect concentration in the mineral of interest, at the conditions of interest. Extended defects, such as dislocations or grain boundaries, may also play a key role, but as these are essentially non-equilibrium features, they will not be considered further here. [Pg.84]

Chien (C7) has proposed an energy mechanism for explaining the initial decrease in film thickness and subsequent formation of waves. Mayer (M7) has dealt with the manner in which the waves, which are initially fairly regular near the inception line, later develop into roll waves, etc., downstream, and Lighthill (L10) has also considered the manner in which waveforms may change by amplitude and frequency dispersion. [Pg.191]

Addition of a catalyst to a reaction mixture increases both rate constants kt and kr because the reaction takes place by a different, lower-energy mechanism. Because kf and kT increase by the same factor, though, the ratio kf/kr is unaffected, and the value of the equilibrium constant Kc = kt/kr remains unchanged. Thus, addition of a catalyst does not alter the composition of an equilibrium mixture. [Pg.558]

Most atmospheric visible and DV absorption and emission involves energy transitions of the outer electron shell of the atoms and molecules involved. The infrared spectrum of radiation from these atmospheric constituents is dominated by energy mechanisms associated with the vibration of molecules. The mid-infrared region is rich with molecular fundamental vibration-rotation bands. Many of the overtones of these bands occur in the near infrared. Pure rotation spectra are more often seen in the far infrared. Most polyatomic species found in the atmosphere exhibit strong vibration-rotation bands in the 1 - 25 yin region of the spectrum, which is the region of interest in this paper. The richness of the region for gas analysis... [Pg.217]

The low energy mechanism is thought to involve the formation of a long-lived singlet intermediate followed by an intersystem crossing to a triplet state and decomposition into products, viz. [Pg.423]

For these values, the dominant contribution comes from a low-energy mechanism. [Pg.392]
