As silicon chip and superconductor development has scaled over the years, it is distinctly possible that we might soon reach a material limit on the computing power of classical computers. Quantum computing could provide a path forward for certain important problems. ...

If a molecule A yields a fluorescent excited state A* that is partially quenched by an added material Q, then a simple kinetic analysis of the quenching data will reveal the second-order quenching constant as follows. Consider the reaction scheme: (29)RateA→hvA*Ia (30)A*→kFA+hυFkF[A...
Using the technique of neutralization-reionization mass spectrometry (NRMS) it could be shown that the elusive phosphorotrithious acid (HS)3P is a stable molecule in the rarefied gas phase. A triple propene elimination from the molecular ions of the dipropyl ester of propylphosphonotrithioic ...
