“…Their results showed that ice XI (i.e. proton-ordered phase of ice Ih) slowly formed in the upper part of a thin ice Ih film without KOH as the temperature gradually decreased below 133 K. [135] Talkenberger et al performed Raman spectroscopic investigations of epitaxial BiFeO 3 thin films on rare earth scandate substrates. Their results were supported by symmetry-based calculations including the analysis of Raman scattering geometry as well as the dielectric function of BiFeO 3 in the IR range.…”

This review, published annually, provides an overview of advances in the field of Raman spectroscopy as found in papers published in the preceding calendar year in the Journal of Raman Spectroscopy (JRS), as well as in trends over the past decade across journals that have published papers important to the field of Raman spectroscopy. This information is obtained from statistical data on article counts obtained from Thomson Reuters ISI Web of Science Core Collection by year and by subfield of Raman spectroscopy. Additional information is gleaned from presentations at the XXV International Conference on Raman Spectroscopy (ICORS 2016) in Forteleza, Brazil in August 2016 and those featuring Raman scattering at SCIX 2016 organized by the Federation of Analytical Chemistry and Spectroscopy Societies (FACSS) in Minneapolis, Minnesota, USA in September 2016. Coverage is also provided for topics from the conference ECONOS 2016 held in April in Göteborg, Sweden and GeoRaman 2016 in June in Novosibirsk, Russia. Finally, papers published in JRS in 2015 are highlighted and arragned by topics at the frontier of Raman spectroscopy. From these various perspectives, it is clear that Raman spectroscopy continues to be a rapidly expanding field that provides sensitive photonic information of matter at the molecular level in an ever‐widening arena of novel applications.

“…To quantify, we calculated the A 3090 /A 3210 (peak area ratios) ratio through multi‐peak fitting for each spectrum, and compared these ratios in Figure 5b. The results clearly indicate a reduction in the A 3090 /A 3210 ratio upon the introduction of these additives, signifying a disruption to the pristine microstructure of the ice Ih phase [49] . Notably, DEE demonstrated the least impact on the ice's microstructure among the tested additives while EG had the most destructive power.…”

Ice has been suggested to have played a significant role in the origin of life partly owing to its ability to concentrate organic molecules and promote reaction efficiency. However, the techniques for studying organic molecules in ice are absorption‐based, which limits the sensitivity of measurements. Here we introduce an emission‐based method to study organic molecules in water ice: the phosphorescence displays high sensitivity depending on the hydration state of an organic salt probe, acridinium iodide (ADI). The designed ADI aqueous system exhibits phosphorescence that can be severely perturbed when the temperature is higher than 110 K at a concentration of the order of 10‐5M, indicating changes in hydration for ADI. Using the ADI phosphorescent probe, it is found that the microstructures of water ice, i.e., crystalline vs. glassy, can be strongly dictated by a trace amount (as low as 10‐5M) of water‐soluble organic molecules. Consistent with cryoSEM images and temperature‐dependent Raman spectral data, the ADI is dehydrated in more crystalline ice and hydrated in more glassy ice. The current investigation serves as a starting point for using more sensitive spectroscopic techniques for studying water‐organics interactions at a much lower concentration and wider temperature range.
