H‐atom tunneling reactions play important roles in astrochemistry, but an understanding of
these reactions is still in its infancy. The unique properties associated with quantum solid …

Cryogenic solid para-hydrogen (p-H2) exhibits pronounced quantum effects, enabling
unique experiments that are typically not possible in noble-gas matrices. The diminished …

The reaction of H atoms with glycine was investigated at 3.1 K in para-H2, a quantum-solid
host. The reaction was followed by IR spectroscopy, with the spectral analysis aided by …

Methylamine CH3NH2 is considered to be an important precursor of interstellar amino acid
because hydrogen abstraction might lead to the aminomethyl radical• CH2NH2 that can …

Glycolaldehyde [HOCH2C (O) H, GA], the primitive sugar-like molecule detected in the
interstellar medium (ISM), is a potential precursor for the synthesis of complex sugars …

The small oxoacids of sulfur (SOS), H x SO y (x, y= 1, 2), are considered to be key reactive
intermediates in organic synthesis, biochemical processes, and atmospheric chemistry …

It is now well-accepted in astrochemistry that the formation of interstellar H2 is taking place
on the surface of interstellar grains. It has also been suggested a long time ago that …

N-Methylformamide, HC (O) NH (CH3), is the smallest amide detected in the interstellar
medium that can exist as cis and trans isomers. We performed reactions of H atoms with …

In this article, a new multi-functional high-vacuum astrophysical ice setup, VIZSLA (Versatile
Ice Zigzag Sublimation Setup for Laboratory Astrochemistry), is introduced. The instrument …

Solid para-hydrogen (pH 2) has emerged as a novel low-temperature matrix host with
unique characteristics associated with a quantum solid. In this chapter, we introduce pH 2 …
