The Investigation of Spin-Crossover Systems by Raman Spectroscopy: A Review
Magnetochemistry, 2022 Spin-crossover (SCO) is a well-documented phenomenon, being intensely investigated by a respectable number of researchers during the last decades. The conventional method for the investigation of SCO properties is by performing magnetic susceptibility ...

Inclusions in ice layers formed by melting and refreezing processes in a Greenland ice core
Journal of Glaciology, 2023 In recent decades, surface melting on the inland Greenland ice sheet has increased, leading to significant meltwater-refreezing in the snow and firn.

AKARI NIR spectroscopy of interstellar ices [PDF]
Proceedings of the International Astronomical Union, 2015 AbstractThe Infrared Camera (IRC) onboard AKARI has a near-infrared (2--5μm) spectroscopic capability with high sensitivity that allows us to study the major ice components in various objects. In particular, H2O and CO2 ice absorption features have been detected towards nearby galaxies, including several young stellar objects (YSOs) in the Large ...

Infrared Spectroscopy on Equilibrated High-Density Amorphous Ice
The Journal of Physical Chemistry Letters, 2022 High-density (HDA) and low-density amorphous ices (LDA) are believed to be counterparts of the high- and low-density liquid phases of water, respectively. In order to better understand how the vibrational modes change during the transition between the two solid states, we present infrared spectroscopy measurements, following the change of the decoupled

A 21 000-year record of fluorescent organic matter markers in the WAIS Divide ice core [PDF]
Climate of the Past, 2017 Englacial ice contains a significant reservoir of organic material (OM), preserving a chronological record of materials from Earth's past. Here, we investigate if OM composition surveys in ice core research can provide paleoecological information on the ...
