  • Our manuscript describing results from the Schnell-Manschewetus 2018 FLASH beamtime has been published online by Nature Communications! The experiments investigated three polycyclic aromatic hydrocarbons, demonstrating a pattern in the preferred dissociation pathways and electronic relaxation on the 10-100 femtosecond timescale for the neutrals, monocations, and dications. The manuscript is accompanied by a short “Behind the Paper” article on the Nature Chemistry Community website.

September 2021

  • Well done to all the group’s attendees at the 27th Colloquium on High-Resolution Molecular Spectroscopy (HRMS), especially the undergraduates, who all presented posters on their work in the group, and Pablo, who gave an oral presentation!

  • Extra congratulations to Melanie, who was awarded the prestigious International Dr. Barbara Mez-Starck Prize 2021 at the HRMS colloquium! The prize was awarded for “her outstanding studies of structural changes in water complexes with increasing amounts of water molecules as well as for her pioneering investigations of enantiomers and the separation of these chirally different molecules”.

  • Members of the FS-SMP group successfully participated in the Schnell-Lee beamtime at the Free Electron Laser in Hamburg (FLASH). This experiment explored the ultrafast relaxation and dissociation dynamics of polycyclic aromatic molecules in the XUV range and involved a large international collaboration between Germany, Sweden, the US and the UK.

  • FS-SMP has moved into a new home!  The group has moved into the newly built Centre for X-ray and Nano Science, CXNS, only a stone’s throw away from our previous home in 25F.

  • Congratulations to Freya, who successfully defended her master’s thesis!  Freya worked in the chirality subgroup, and will continue with the group for her PhD (after a short but well deserved break)!

July 2021

  • Congratulations to Dalona, who successfully defended her bachelor’s thesis!  Dalona worked in the astrochemistry subgroup looking at discharge reactions on the COMPACT spectrometer.

  • Congratulations to Dona for giving a superb invited talk on the topic of electrical discharge of polycyclic aromatic hydrocarbons at the International Symposium on Molecular Beams (ISMB)!

June 2021

  • Well done to all the group’s contributors at the International Symposium on Molecular Spectroscopy (ISMS) 2021! 

May 2021

  • The group bids farewell to Mariyam!  We wish her all the best in her new postdoc position at the University of Cologne!

April 2021

  • Welcome to Laura from the Christian Albrechts University in Kiel, who joins the astrochemistry subgroup for a master’s project!
  • We also bid farewell and good luck to Cristóbal, who leaves us for a position at the University of Valladolid!
  • And welcome (welcome back) to Chris, who rejoins the group from the University of New South Wales for a research visit!

  • The group recently had two papers accepted to the Journal of Molecular Spectroscopy’s Festschrift celebrating Stephan Schlemmer’s 60th Birthday with the theme “Laboratory Spectroscopy for Astrophysics”! Congratulations to everyone involved in these collaborative projects! The first focuses on the characterization of the lowest vibrationally excited state of propylene oxide, and the work was conducted with the group of Thomas Giesen at the University of Kassel. In the paper, the complicated spectrum is deciphered, including the effect of the methyl group’s free rotation. The second piece extends our previous publication on the N-heterocycle imidazole by considering the rotational spectra of its vibrationally excited states and heavy-atom isotopologues across the 2-295 GHz range. The data presented is essential for observational searches for these species, and, in addition, comprehensive structural analyses and comparisons to similar molecules are presented. The project included collaborations with the Center for Astrochemical Studies at the Max Planck Institute for Extraterrestrial Physics, Ca’ Foscari University of Venice, the University of Virginia, and the University of Rennes. And a special shout out to Gayatri for her first publication in the group!

  • Farewell Weixing! Good luck at your new job at Fudan University, building up an amazing broadband rotational spectrometer
  • The group has its first paper accepted in The Astrophysical Journal! The publication centers on the rotational spectra of three amino alcohols - alaninol, valinol, and leucinol - between 2-110 GHz. Accurate rotational constants and line lists are delivered to enable astronomers to search for these doubly-functional molecules and their isotopologues and vibrationally excited states in the interstellar medium. This publication’s sister paper, which introduced our 18-26 GHz spectrometer and reported on our work on isoleucinol, was published in PCCP last year. Congratulations to everyone for the completion of this ambitious project!

January 2021

  • Welcome to Alcides Simao and Eva Gougoula as new Postdocs! Both will be supporting our astrochemistry subgroup. Alcides will be bringing the commissioning of our IR-UV spectrometer up to speed, and Eva will be working on the rotational spectroscopy side of it.

  • Congratulations Dan! We wish you the best in your new position as Junior Professor at the Uni Göttingen!
  • Bon voyage and best of luck Sérgio in your home town Portugal and in your future career as a scientific researcher at the University of Coimbra!
