ASTRONOMY:
A Key Molecular Ion in the Universe and in the Laboratory
T. R. Geballe1* and T. Oka2*
The molecular ion H3
is abundant in interstellar clouds and presents many interesting puzzles in the laboratory. A recent conference explored the current knowledge about this species and its implications for astrophysics.
