Vibrational spectroscopy has become one of the key techniques for the structural recognition of molecular systems and measuring their interactions. Its spectral range, corresponding to vibrational transitions, leads to knowledge of the functional groups of the analyzed systems. Since the discovery of infrared radiation, two centuries ago, then Raman scattering a century later, these techniques have undergone extraordinary breakthrough to a variety of applications on small molecules and on macromolecules alike.

We encourage our peers to contribute either original research articles or review articles that will recapitulate the continuing advancement to interpret molecular and even material structure using vibrational spectroscopy mainly infrared absorption. We are particularly interested in articles tackling the junction of the three domains: physics, chemistry, and biology. Attention will be devoted to the applications of optical spectroscopy in the fields of biomedical diagnosis, microscopy imaging, environmental research, food and pharmaceutics, computational predictions, synchrotron development, and nanotechnology. Prospectively, the topics will include, but are not limited to:

• Molecular structural characterization and interactions
• Two dimension and microspectroscopy innovations
• Optical activity and chirality determination
• Vibrational techniques and chemometrics advancements
• Modeling and data processing achievements
• Recent surface, interfaces enhancement tools and methods
• Nanoparticles- and nanotechnology-related issues expectations
