From the laboratory to the interstellar medium: a strategy to search for exotic molecules in space
Frontiers in Astronomy and Space Sciences, 2023 The chemistry of the interstellar medium occurs under extreme conditions and can lead to the formation of exotic molecules. These are species that on Earth are unstable and/or highly reactive. Their discovery in space is usually based on the astronomical

Rotational spectroscopy with an optical centrifuge [PDF]
Physical Chemistry Chemical Physics, 2014 We demonstrate a new spectroscopic method for studying electronic transitions in molecules with extremely broad range of angular momentum. We employ an optical centrifuge to create narrow rotational wave packets in the ground electronic state of $^{16}$O$_2$.
