  • von Helden, Gert (International Symposium on Molecular Spectroscopy, 2021-06-24)
    The coupling of ion mobility with mass spectrometry (IM-MS) allows for the selection of isolated, gas-phase molecular ions with defined mass/charge as well as geometrical size/charge ratios. When coupled to cryogenic ion ...

  • Tsybizova, Alexandra (International Symposium on Molecular Spectroscopy, 2021-06-24)
    In cryogenic ion vibrational predissociation (CIVP) spectroscopy, the tag's influence on the spectrum is an important consideration. Whereas for small ions, several studies show that the tag effects can be significant, ...

  • Ozeki, Masayoshi (International Symposium on Molecular Spectroscopy, 2021-06-24)
    Since gas-phase hydrogen-bonded clusters are treated as microscopic models of hydrogen bond networks, numerous spectroscopic studies have been performed, so far. Structural fluctuations are one of features of hydrogen bond ...

  • Radloff, Robert G. (International Symposium on Molecular Spectroscopy, 2021-06-24)
    The chemistry of matter surrounding stars depends strongly on the elements that the center star produces during its lifetime but also on the transport of these elements to the outer layers of the star. Stars like IRC+\,10216 ...
