The MALDI-TOF mass spectrum of 4 afforded the expected molecular ion peak plus one lithium ion. The numbers and the intensity of the isotope peaks of the spectrum are also in good agreement with ...

Using their newly proposed method, König and her colleagues demonstrated the confinement of an externally produced molecular hydrogen ion (HD +) for more than a month. In addition, they were able ...

This method, outlined in a paper published in Physical Review Letters, could open new possibilities for the manipulation and measurement of rich quantum states in individual molecular ions. "The ...

or what makes ion channels so efficient and selective for a particular type of ion. "Molecular dynamics simulations can mimic the experimental setup atom by atom and thus provide insights into ...
