|
 | The fundamental parameter generally accepted in physical chemistry to account for the departure of a solution from ideality due to ionic dissociation and other causes is the mean ionic activity coefficient of the solute, rather than the van't Hoff factor commonly used in the literature and textbooks on cloud physics. It is directly related to many properties of a solution, one of which is the lowering of vapor pressure. The ... |

| COMPARISON BETWEEN EXPERIMENTAL AND CALCULATED SPECTRA OF CARBON DIOXIDE AND WATER VAPOR, |

Thomas G. Kyle; DENVER UNIV COLO DEPT OF PHYSICS
|
| Line by line calculations of absorption spectra were carried out for the 2.0 and the 2.7 micron bands of carbon dioxide and for the 2.7 micron band of water vapor. The parameters for these calculations are taken from published listings for these bands. The calculations are compared with experimental data of the same spectral resolution, this being a fraction of a wavenumber. The comparisons show the line positions to be ... |

|
| A new integrated system for oxygen recovery from carbon dioxide was investigated. Experimental studies indicated that it was feasible to integrate water electrolysis with carbon dioxide hydrogenation in an electrolysis cell using Pd-25Ag hydrogen-diffusion cathodes containing Sabatier catalyst. A closed system producing carbon appeared feasible from experiments on catalytic methane cracking followed by hydrogen separation from unreacted methane in an electrolytic hydrogen-concentration cell using Pd-25Ag electrodes. A small experimental breadboard ... |

A. J. Blake; J. H. Carver; ADELAIDE UNIV (AUSTRALIA) DEPT OF PHYSICS
|
| A photoelectron energy spectrometer was used to determine partial photoionization cross sections of molecular oxygen, nitrogen and water vapour for monochromatic incident radiation in the wavelength range 584 - 900A. For each gas, cross sections were determined for transitions to particular ionic states which were identified by measuring the corresponding photoelectron energy. For molecular oxygen, cross sections were determined for transitions to the X(2)Pi-g, (a(4)Pi-u + A(2)Pi-u) b(4) Sigma(-)g and ... |

| EMPIRICAL INFRARED ABSORPTION COEFFICIENTS OF H2O FROM 300K TO 3000K. |

|
| A set of absorption coefficients for water vapor as functions of temperature has been empirically deduced from existing quantitative absorption and emission spectra between 1 and 22 microns. The basic assumption was made that, for optically thick gases, the curve of growth is given by a statistical model. The absorption coefficients were obtained for each vibration-rotation band by adjusting the band averaged line half widths and line spacings such that ... |

| AREAL DISTRIBUTION AND DIURNAL VARIATION OF WATER VAPOR NEAR THE GROUND IN THE CONTIGUOUS UNITED STATES. |

|
| Maps showing the distribution in the United States (except Hawaii and Alaska) of average monthly dew point and its standard deviation, average monthly vapor pressure, and types of diurnal variation and range of dew point are presented and discussed. The maps are based on hourly psychrometric observations at nearly 200 stations for lengths of record of about ten years. The principal features of the maps are evidence of different humidity ... |

| STUDIES OF INFRARED RADIATIVE TRANSFER IN HOT GASES. I: SPECIAL ABSORPTANCE MEASUREMENTS IN THE 2.7-MICRON H2O BANDS. |

|
| Measurements of spectral absorptances in the 2.7-micron water vapor bands were made at moderate resolution, for pressures from 50 mm to 1 atm, temperatures from 750 to 1300 K, and path lengths of 7.75 and 60.0 cm. Samples of pure water vapor were contained in quartz cells heated in a furnace which was built into a specially designed double-beam spectrometer. The resultant spectra are presented and correlated with those obtained ... |

| THE EFFECT OF SELECTED DILUENT GASES ON THE SELF-INDUCED ISOTOPIC EXCHANGE BETWEEN TRITIUM AND WATER VAPOR. |

C. H. Smith; L. H. Gevantman; NAVAL RADIOLOGICAL DEFENSE LAB SAN FRANCISCO CALIF
|
| The effect of various diluent gases on the rate of the self-induced exchange between tritium and water vapor was investigated. The gases studied were: helium, neon, argon, krypton, xenon, air, nitrogen, oxygen, hydrogen, and ammonia. The average value found for a second-order rate constant, for inert gases agreed with that found previously (See AD-246 259). Air and nitrogen as diluents yielded rate constants of 0.00127 and 0.00086 ml/mc/hr, respectively. Oxygen ... |
