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 ...

Vibrational dynamics of ice in reverse micelles [PDF]
, 2008 he ultrafast vibrational dynamics of HDO:D2O ice at 180 K in anionic reverse micelles is studied by midinfrared femtosecond pump-probe spectroscopy. Solutions containing reverse micelles are cooled to low temperatures by a fast-freezing procedure.

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 ...

Transient absorption of vibrationally excited ice Ih [PDF]
, 2008 The ultrafast dynamics of HDO:D2O ice Ih at 180 K is studied by midinfrared ultrafast pump-probe spectroscopy. The vibrational relaxation of HDO:D2O ice is observed to proceed via an intermediate state, which has a blueshifted absorption spectrum ...
