It was noted that an understanding of gas phase unimolecular
reaction (e.g., rearrangements) was critical in interpreting the mass spectra.
In addition, there are unimolecular
and bimolecular termination reactions where free radicals recombine or disproportionate into neutral or inactive species (Eqs 3 to 5).
Recent theoretical studies in Pritchard's group have been devoted to two aspects of unimolecular
The new "unimolecular
micelles," which dissolve in water, are composed of benzene-based building blocks that normally display a powerful aversion to water.
Ribonucleosides, due to their thermodynamically preferred anti N-glycosidic conformation, originating from the C3'-endo sugar pucker (Figure 9, 3), can change the folding topology if incorporated into syn dG positions of deoxy-GQs, for instance, as described for the TBA GQ whose antiparallel fold could be changed to parallel and the unimolecular
topology to bimolecular .

Decomposition of TNT (2,4,6-Trinitrotoluene): A DFT Study., J.
First, in the preparation of the aggregates, the copolymers were unimolecular
in the toluene before the addition of DMF.
Included in the issue are 14 highly scientific articles on such diverse topics as the drying and cracking of soft latex coatings, novel findings on the utility of colloidal unimolecular
polymers, and the use of bio-based technologies such as monomer-grafted sucrose ester resins.
Surface catalyzed reactions can often be adequately described by a unimolecular
Langmuir-Hinshelwood (L-H) mechanism, in which an adsorbed reactant with fractional surface coverage 6 is consumed at an initial rate given by
Poly(amidoamine) organosilicon (PAMAMOS) dendrimers are silicon containing first commercial dendrimers which are inverted unimolecular
micelles that contain exterior hydrophobic organosilicon and interiorly hydrophilic, nucleophilic polyamidoamine .
The degradation of some biomarkers at room temperature (folate and 3-hydroxyanthranilic acid in EDTA plasma and FMN) or in frozen samples (3-hydroxykynurenine) does not obey first order kinetics, suggesting that the decomposition is not a simple unimolecular
event in a stable or homogeneous matrix.
