The alcoholate-induced dehydrochlorination of styryl chloride possibly occurs by the 3 different competing mechanisms: E2, E1cb, and E1cb-HBA an E1cb modification. These conclusions were confirmed by H-D exchange, isotope effects, order of reaction, and re ...
Isotope sepn. was demonstrated following the selective IR laser-induced photodissocn. of van der Waals clusters in a free jet. Irradn. of a natural abundance mixt. of SF6 isotopomers dild. in Ar with a 20-W cw CO2 laser gave overall enrichment factors >1.1 ...
The feasibility of a new, 2-laser, isotope sepn. scheme was tested. The 1st laser induces isotopically selective condensation in the collisional region of a free jet of SF6 dild. in Ar. Thus, a mol. beam contg. non-clustered 32SF6 and clustered 34SF6{m}Ar{ ...
Efficient laser isotope sepn. is demonstrated in 2 distinct schemes. Irradn. of the collisional zone of the gas expansion provokes an isotopically selective condensation, as well as changes in the velocity distributions of the free jet. The resulting large ...
The separation of hydrogen isotopes for applications such as nuclear fusion is a major challenge. Current technologies are energy intensive and inefficient. Nanoporous materials have the potential to separate hydrogen isotopes by kinetic quantum sieving, b ...
