IX-L-7. Plot of the estimated photolysis frequencies for benzaldehyde photodecomposition as a function of solar zenith angle. Cloudless sky in the lower troposphere and an overhead ozone column of 350 DU was assumed in the calculation. Measurable photodecomposition in the troposphere occurs by only the two primary processes shown processes .

IX-l-8. Comparison of the absorption cross sections for 1-methyl-cyclohexyl-1,2-dinitrate and fran5-2-hydroxy-cyclopenty 1-1-nitrate with that of cyclopentyl nitrate.

IX-L-8. Cross sections for some aromatic dicarbonyl compounds as measured in hexane solution . Phthalide, a product of the photolysis of phthaldialdehyde, is not photochemically active at the wavelengths of sunhght available in the troposphere. Actinic flux is given for an overhead Sun in the lower troposphere with an overhead ozone column of 350 DU.

IX-l-9. Comparison of the absorption spectrum of 1,2-propandiol dinitrate with that of the two structurally related mononitrates, n- and wo-propyl nitrate.

IX-L-I I. Plot of the absorption cross sections for benzaldehyde and a two substituted benzaldehydes from measurements in nonpolar solvents .

IX-L-I. Comparison of the vapor-phase absorption spectra of toluene and some of its oxidation products

IX-L-IO. Approximate photolysis frequencies as a function of solar zenith angle for 2-aetylbenzaldehyde photodecomposition as calculated for a clear skies in the lower troposphere with an overhead ozone column of 350 DU we have assumed a wavelength independence of the average quantum yield of photodecomposition 0.21 as measured in broadband experiments referenced to7 .

IX-L-IS. Cross sections for 2-methyl-1-nitronaphthalene as measured in ethanol solution by Ldng .

IX-M-1. The diurnal photochemical lifetime for CH2O as calculated for clear sky conditions in the lower troposphere with an ozone column of 350 DU. Values are shown for locations at latitudes of 30 , 40 , and 50 over an 18-month period.

IX-M-2a. Diurnal variation of the solar zenith angle with latitude for January 1.

IX-M-2b. Diurnal variation of the solar zenith angle with latitude for March 20.

IX-M-2c. Diurnal variation of the solar zenith angle with latitude for June 20.

Ixical density of states on the clean metal surface at the Fermi level and IR stretch frequency of CO adsorbed on the same surfaces. For samples of Pl zeolite with different zeolite acidities, the clean metal-surface Ef LDOS was found from curves as in 1 ig. 57. Next, CO was adsorbed on these same samples, and the stretch frequency was measured as a function of coverage. The value plotted here is an extrapolation to zero coverage. This plot indicates that the C-O intramolecular bond after chemisorption will be weaker if the initial clean-surface LDOS is higher.

IXS spectra of H2O, D2O and a mixture with molar composition of 50 H2O after subtracting the contributions of the central peak. Gaussians are fitted to the data as a guide to the eye.

IZ Dynamics oT Helium molecules in bisphenol-A-polycarbonate computed by MD and TSA under otherwise identical conditions

IZ Influence of the number of treated hollow fiters on the gas penneabflity of the cmn-posite membranes 70J

IZ Simplified internal structure of the moon, showing the mineralogically zoned source regions from which the mare basalts were derived, the feldspar-rich crust, and KREEP. Lanthanide abundance patterns for these various regions are depicted on the right with the approximate concentrations relative to average chondrites indicated. The lunar interior is undoubtedly more complex both vertically and laterally than depicted.

IZ Specular transmission refers to light passing through an object without diffusion. Specular transmission measurements are widely used in the chemical analyses and color measurements of liquids. Potentially, appearance attributes important for specular transmission should be roughly analogous with gloss attributes associated with specular reflection .

IZ The appearance potential spectra in the vicinity of the Co 2p core levels for samples as indicated configuration.

IZl Glue line breaches where feed water and p ermeate can mix.
