Malgorzata Biczysko - Computational Spectroscopy Across the Micro- to Nanometer Wavelength Range in Astrochemical Environments: The ISM, Ices, and Planetary Soils

Recent space and planetary missions, including JWST observations of the interstellar medium (ISM) and Mars exploration by Perseverance, underscore the increasing importance of vibrational and electronic spectroscopic measurements in astrochemistry. In this context, computational spectroscopy provides essential support for laboratory experiments by aiding spectral assignment, guiding measurements, and extending accessible energy, temperature, and resolution regimes beyond current experimental limits to conditions relevant to astrochemical environments.
This seminar will present selected examples involving complex organic molecules, including semi-rigid and flexible prebiotic species, with spectroscopic properties spanning wavelengths from the mid-infrared (≈20 µm) to the vacuum ultraviolet (≈100 nm). These examples illustrate how computational spectroscopy complements laboratory studies, astronomical observations, and planetary exploration in diverse astrochemical environments.
