A quantitative evaluation of the vigorousness of the contributor or the nakedness of fluoride ion contributors is discussed. The outcome indicates that not much is achieved by enhancing the cation size after a specific level and the less important elements like the chemical and physical aspects override it.

A potentiometric study of the coordination of the fluorophore, 2-methyl-8-(4-toluenesulfonamido)-6-quinolyloxyacetic acid is reported. This study shows that assessments of intracellular zinc (II) levels through Zn(super 2+) is semiquantitative and detects ensembles of the same species.

The femtosecond dynamics of the photochemistry of a simple merocyanine dye trans isomer is examined. The occurrence of deprotonation compared to isomerization is investigated.

Research describing the theoretical and matrix-isolation study of CO(sub 2)-NO van der Waals complex is presented.

Alpha-oxoketenes have interesting structural features, synthetic utility and high reactivity. 6-oxocyclohexa-2,4-dienylideneketene was generated by laser flash photolysis and observed in solution. Its reactivity with H(sub2)0, MeOH and Et(sub2)NH with relative reactivities of 1.0, 2.0 and 73, was measured. The hydration is thought to occur by in-plane attack of the H(sub2)0 molecule on the ketenyl carbonyl via a pseudopericyclic transition state.

Complexation of an arene by an electron-deficient transition metal center has been much researched over the past 30 years. Anisoles were complexed by pentaammineosmium(II) and the result 5,6-eta2-anisole compounds were treated with activated olefins or acetals, forming 4H-anisolium compounds. They were able to undergo inter or intramolecular nucleophilic addition reactions, and 2-methoxy-1,3-cyclohexadiene complexes were formed. These can be readily converted into functionalized cyclohexenones, cyclohexadienes, and cyclohexenes.
