In the chemistry of interstellar clouds, the three-atomic hydrogen ion plays a key role. In these reactions, also simple organic molecules form. Although H3+ is the simplest polyatomic molecular ion, ...

A polyatomic ion that was thus far inaccessible with conventional mass spectroscopy has now been uncovered using extremely short laser pulses. Catching a glimpse of this ion would open up new ...

Bombarding a material with an ion beam provides valuable information about its surface composition. Ion guns that fire polyatomic ions can reveal more detailed information and cause less damage to the ...
