A matrix isolation and Ab initio study on C2H6…HCN complex: An unusual example of hydrogen bonding

Fabrication of poly(vinyl alcohol) bottle with high barrier property and mechanical property via compound plasticization

“…Solid polyols all presented a wide and flat peak in the region between 3501 and 3194 cm −1 , corresponding to the stretching vibration peak of OH. There was no obvious variation except for the “red shift” [ 18,19 ] of the stretching vibration peak of OH after plasticization, which suggested the destruction and reconstruction of initial hydrogen bonds in PVA. Compared with neat PVA, the vibration peak of OH shifted from 3418 to 3352 cm −1 in 30GLY group, indicating that the initial hydrogen bonds within PVA were partially replaced by the interactions between glycerol and PVA.…”

Weakly Bound Complex Formation between HCN and CH3Cl: A Matrix-Isolation and Computational Study

“…One of the most abundant molecules detected in space is hydrogen cyanide (HCN). − Numerous studies show noncovalent bonding interactions between HCN and other molecules. These interactions range from hydrogen-bonding to halogen-bonding interactions, where HCN can donate or accept electron density. − Complexation of HCN with other molecules can also affect the transformation of HCN, in some cases catalyzing the isomerization from HCN to HNC, which has important consequences to our understanding of the sources and sinks of these two isomers. − Studying the reactivity of HCN and its oligomers in astrophysical objects is of interest as HCN is an important building block for amino acids and other life-bearing polymers. − In order to advance studies of amino acid and life-bearing polymer formation in space, a complete chemical understanding of their precursors, such as HCN, under interstellar conditions is necessary.…”
