Current areas of interest include ion-induced polymerization, reactivities of structural isomers, the unimolecular decomposition of polycyclic aromatic hydrocarbon ions, gas-phase coordination to Fe and other metals (M) contained in derivatized Fe[X.sup.+] and M[X.sup.+] ions, interstellar and circumstellar ion chemistry, and fundamental aspects of the ion chemistry of large carbon clusters known as fullerenes [ILLUSTRATION FOR FIGURE 4 OMITTED].
The 22-mer[G.bar]GGAT[G.bar]]GGACACAGGGGAC[G.bar]GG oligonucleotide folds into a unimolecular hybrid-type GQ in [K.sup.+] solution.
6a (Sample 1 shown in Table 4), the size for a majority of micelles located at 50-400 nm, while the existence of small percentage of size (<10 nm) indicated that not all the blocks had formed the micelles and some chains of the copolymer were still unimolecular. Here, the reason for the diameter obtained from DLS which was bigger than TEM, was the different condition of two measurements.

Dendrimers with an apolar core and polar shell have been referred to as "unimolecular micelles" whereas the dendritic structure is independent of dendrimer concentration unlike conventional micelles [64].
(14) A unimolecular photoinitiator mixture (Irgacure 500), 4% of the total amount of TMPTA and acrylated polyester, was incorporated into the formulations for UV curing.
According to Langmuir theory of unimolecular adsorption, value of n should be between zero and one.
Chapter 3 covers reactions in MS/MS and is followed by a chapter on applications to fundamental studies in ion chemistry, topics including unimolecular and bimolecular reactions, various reaction regions, and the thermochemistry of ions.
The results correspond to an unimolecular elementary process, when degradation is greater at a lower concentration.
