Recent highlights
- The investigation Rotational Spectroscopy of the Thioformaldehyde Isotopologues H2CS and H2C34S in Four Interacting Excited Vibrational States and an Account on the Rotational Spectrum of Thioketene, H2CCS is a text book example for Coriolis interaction. The study highlights the importance of rotational spectroscopy for deeper insight into rovibrational interactions as does the preceeding work on methyl cyanide. The preceding publication Laboratory Spectroscopic Study of Isotopic Thioformaldehyde, H2CS, and Determination of its Equilibrium Structure is also recommended.
- Toward a Global Model of the Interactions in Low-lying States of Methyl Cyanide: Rotational and Rovibrational Spectroscopy of the v4 = 1 State and Tentative Interstellar Detection of the v4 = v8 = 1 State in Sgr B2(N). This work describes an exploration of the intricate interactions of v4 = 1 with neighboring states, in paricular with v8 = 2 and 3. An ealier account was given in Rotational Spectroscopy as a Tool to Investigate Interactions between Vibrational Polyads in Symmetric Top Molecules: Low-lying States v8 ≤ 2 of Methyl Cyanide, CH3CN.
- A study on isotopologs of oxygen-containing organic molecules with D and 13C in the star-formation region IRAS 16293–2422 employing the Atacama Large Millimeter Array (ALMA). Many isotopologs have been detected for the first time in space.
- Extragalactic detection of sulfanylium (SH+) and interstellar detection of 34SH+ in the z = 0.89 foreground galaxy in the direction of the quasar PKS 1830–211.
- Extragalactic detection of argonium (ArH+) in the z = 0.89 foreground galaxy in the direction of the quasar PKS 1830–211.
