Using vibrational spectroscopy as the main tool, contributions are made to a variety of problems ranging from cutting-edge basic to more application-oriented research.

Through their distinct light-matter interactions, Raman (inelastic photon scattering) and infrared (resonance photon absorption) spectroscopies are complementary techniques sensitive in probing vibrational excitations in a material (gas, liquid, crystalline or amorphous solid), through their interaction with photons usually lying in the energy difference range of a few hundred meV from the fundamental electronic configuration level (except NIR spectroscopy, which uses photons in the range 500-1500 meV). These excitations correspond to atomic motions that can be either collective or more localized depending on the crystallinity of the material (higher crystallinity or longer range-order favoring a more collective atomic motion) and are related to the way the various atomic species are geometrically arranged and vibrate with respect to each other so as to form part of the structure of the material. This is why vibrational spectroscopies are a very useful tool offering structural information of materials at the molecular level non-destructively (albeit indirectly).

The main focus of this work over the years is to determine or clarify symmetry (e.g. regular vs distorted molecular group polyhedron) or geometry (e.g. tetrahedral vs octahedral arrangement) variations of materials structural entities at the micro/meso/nano-scale and arrive at correlations with some of their properties. These inhomogeneities are related to either structural variants of the same chemical composition (isomeric groups) or to the coexistence of different chemical phases or both. As vibrational spectroscopies are an indirect probe of the structure, an effort is made to correlate the in-house vibrational spectroscopies with other techniques such as XRD, NMR, AFM, etc., through either collaborations or literature search.

Starting from the collaboration with other TPCI researchers with expertise in vibrational spectroscopy (especially in glassy materials), a diverse network of collaborators has developed over the years and activity has expanded in areas ranging from applications in cultural heritage to hybrid perovskite vibrational spectroscopy to mineralogy, to name some examples. Part of this activity is to provide research support in vibrational spectroscopy to other TPCI researchers. On several occasions Dr. Palles acts as the liaison person between TPCI and external collaborators, in charge of initiating or performing vibrational spectroscopy measurements.

Based on the expertise acquired from (a) the study of the short- and medium-range order of oxide glasses, (b) applications in mineralogy and (c) vibrational spectroscopy in general, activity extended to the study of archaeological glass and other archaeological materials. Involvement in this area is the product of the decision to contribute to an applied field like archaeometry through collaboration with either TPCI or the Institute of Historical Research (NHRF) researchers or external partners active in archaeometry.
