Special Issue Information
Dear Colleagues,
The investigation of gas-phase biomolecules using advanced X-ray spectroscopy techniques has emerged as a pivotal field for understanding fundamental electronic structures and dynamics relevant to biological function. This Special Issue brings together state-of-the-art experimental studies that exploit the full potential of modern X-ray sources, including synchrotrons, high-harmonic generation (HHG) setups, and free-electron lasers (FELs), alongside advanced theoretical investigations that provide interpretation and predictive insight. Complementary light sources enable exploration of biomolecules across varying time scales and energy resolutions, ranging from steady-state core-level spectroscopy at synchrotron facilities to ultrafast dynamical studies at FELs and HHG-based laboratories.
The field is of key importance in probing phenomena such as site-specific ionization and dissociation, charge migration, and electronic relaxation, while also shedding light on the intricate interplay between electronic and geometric structures. Theoretical advancements presented alongside experimental findings offer crucial insights into spectral features, electronic decay channels, and the role of nuclear motion, bridging the gap between observation and molecular-level understanding.
This Special Issue, titled “X-Ray Spectroscopy of Gas-Phase Biomolecules”, spans varying molecular targets, ranging from small biological building blocks to complex biomolecular systems, examined through both experimental and theoretical lenses. Collectively, the Special Issue articles will demonstrate the synergy between cutting-edge instrumentation and advanced computational modeling in uncovering the rich X-ray spectroscopic behavior of gas-phase biomolecules, laying the foundation for future breakthroughs in chemical physics, biology, and materials science.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
