Nuclear spin isomers of water molecules, i.e., ortho- and para-H2O, are quantum states of one of the most important molecules. Presently, our understanding of the water isomer properties, especially ...

Each of the three isomeric pyridyl radicals (2-, 3-, and 4-dehydropyridines) contains a lone pair and an unpaired electron. As a result, a potential two centered–three electron interaction between the ...

The reactions of the methylidyne radical (CH) with ethylene, acetylene, allene, and methylacetylene are studied at room temperature using tunable vacuum ultraviolet (VUV) photoionization and ...
