With the advent of JWST ice observations, dedicated studies on the formation reactions of detected molecules are becoming increasingly important. One of the most interesting molecules in interstellar ice is CO _2 . Despite its simplicity, the main fo

Heterogeneous radical processes on ice surfaces play a vital role in the formation of building blocks of the biologically relevant molecules in space. Therefore, quantitative mechanistic details of the radical binding and radical reactions on ices ar

The CH _3 O and CH _2 OH radicals can be important precursors of complex organic molecules (COMs) in interstellar dust. The COMs presumably originating from these radicals were abundantly found in various astronomical objects. Because each radical le

Faraday Discussions.
A systematic survey was performed for binding energy and reaction path search calculations on ice. ONIOM(⍵B97X-D/Def2-TZVP:AMOEBA09) calculations suggested a range of binding energies for CH2OH radical (0.29 – 0.69 eV)...

The existence of molecular orientational order in nanometer-thick films of molecules has long been implied by surface potential measurements. However, direct quantitative determination of the molecular orientation is challenging, especially for metas

The surface of most aerial plant organs is covered with the cuticle, a membrane consisting of a variety of organic compounds, including waxes, cutin (a polyester) and polysaccharides. The cuticle serves as the multifunctional interface between the pl
Three structural isomers of the C2H4O2 molecule, namely, methyl formate (MF; HCOOCH3), acetic acid (AA; CH3COOH), and glycol aldehyde (GA; HOCH2CHO), have attracted considerable attention as targets for understanding pathways towards molecular comple

The clear evidence for the nuclear spin conversion of matrix-isolated ${\mathrm{H}}_{2}$ is presented. We trapped ${\mathrm{H}}_{2}$ in a ${\mathrm{CO}}_{2}$ film at 5.4 K and detected the induced infrared-absorption band including both the component
