Advances in Infrared Spectroscopy and Raman Spectroscopy

Dear Colleagues,

Molecules vibrate at specific modes, typically in the infrared (IR) frequency range, allowing us to develop advanced label-free techniques to sense them based on absorption or scattering. For example, IR spectroscopy relies on molecular absorption, while Raman spectroscopy utilizes inelastic scattering between the molecule and photons. Both are widely used to determine the vibrational modes of the detected molecules and quantify their signal intensities. Because a particular molecule or material provides a distinct chemical fingerprint, these label-free methods can be used to characterize and identify the material or distinguish it from others. When combined with confocal microscopy, label-free techniques can be extended to applications achieving real-time, chemical-specific, in situ imaging/mapping with sub-wavelength resolution.

This Special Issue invites manuscripts that introduce the recent advances in “Advances in Infrared Spectroscopy and Raman Spectroscopy”. The topic covers, but is not limited to, molecule detection, identification, and characterization; biomedical screening; light–matter interaction; vibrational coherence; IR spectroscopy; Raman spectroscopy; and time-resolved spectroscopy. All original research and review articles are accepted.

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. Photonics is an international peer-reviewed open access monthly 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 2400 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.
