We have established an apparatus for terahertz and mid-infrared spectroscopy in an ultrahigh vacuum and have measured absorption spectra of D2O clusters trapped in solid Ar. To assign terahertz absorption peaks due to the D2O dimer, trimer, and te...

We measured infrared absorption spectra of crystalline II of CH4 and succeeded in detecting a prominent Q(2) peak in the (3) vibrational region by rapid cooling after annealing as well as previously reported rovibrational and librational-vibration...
The infrared absorption spectra of D2O monomers and clusters isolated in rare-gas matrices were systematically reinvestigated under the control of the following factors: the D2O concentration, deposition rate, heating temperature, and rare-gas spe...

Abstract: Nuclear spin relaxation of methane in solid xenon has been studied by infrared spectroscopy. From the analysis of the temporal changes of the rovibrational peaks, the rates of the nuclear spin relaxation of I = 2 ← 1 correlated to the ro...
<p>Surface science had its beginning at the dawn of the human civilization and vacuum science in the 17th century. Collaboration between them has begun in the late 19th century and has grown in close manner in the field of sc...

Nuclear spin conversion in H2 has attracted much interest for a long time, but the unified view of its mechanism has not been attained yet. The authors trapped H2 in solid CO and CO2 and on H2O ice to ob...
