A consistent embedding hierarchy is applied to the calculation of binding enthalpies for organophosphate molecules to a silica surface and compared to experiment. The interaction of four probe molecules, dimethyl methylphosphonate (DMMP), diisopropyl

Low level ab initio Quantum Chemistry (QC) is shown to be a promising technique for predicting the relative ordering of a wide variety of potential analyte, dopant, and interferent molecules, by their proton affinities (PA). Computed PAs, using a sin

This article confirms the physical significance of a new method for determining adsorption energy distributions in porous materials. The premise of the model is that an adsorption isotherm consists of several equilibrium processes corresponding to ad

Equilibria involving three probe gases adsorbed on two porous carbonaceous supports are measured at various temperatures. A novel analysis of the data is offered which uses multiple process equilibria to calculate adsorption equilibrium constants for

Rate constants for the reactions of OH radicals with dimethyl phosphonate [DMHP, (CH(3)O)(2)P(O)H] and dimethyl methylphosphonate [DMMP, (CH(3)O)(2)P(O)CH(3)] have been calculated by ab initio structural methods and semiclassical dynamics modeling an

Semiempirical INDO/S spectral calculations have been carried out for the all-trans carotenoids, 3,4,7,8-tetrahydrospheroidene, 3,4,5,6-tetrahydrospheroidene, and 3,4-dihydrospheroidene, as well as the all-trans and 15,15'-cis isomers of spheroidene.

Photophysical and photochemical properties of 1-phenylpyrazole and 3-,4-, and 5-methyl-1-phenylpyrazoles have been investigated. INDO/S calculations agree with experimental measurements which show that the S 1 and T 1 states of these compounds are π
