Electron–phonon (e–p) polar-coupling interactions in C12H17ClN4OS·HCl·H2O crystals exhibiting an upward frequency shift with increasing temperature are investigated using terahertz and far-infrared spectroscopies, and the structural condition r

Abstract Polysilyne with repeating disilyne units, a silicon analogue of polyacetylene, has a high potential for application to various novel silicon-based electronic devices because of the unique properties of Si=Si units with a smaller HOMO–LUMO

Abstract Van der Waals (VDW) interactions provide fantastic properties for biological systems that function at room temperature. The VDW interaction, which primarily contributes to weak hydrogen bonding, is expected to play a key role in regulating h

The development of terahertz technology in the last few decades has made it possible to obtain a clear terahertz (THz) spectrum. THz vibrations clearly show the formation of weak bonds in crystals. The simultaneous progress in the code of first-princ

Low-frequency vibrations of crystalline molecules are very sensitive to the local environment in which the molecules, for example, hydrated ions captured in crystals, find themselves. We present low-temperature X-ray crystallographic measurements on

The paper reviews the polyanionic hexagons of silicon and germanium, focusing on aromaticity. The chair-like structures of hexasila- and hexagermabenzene are similar to a nonaromatic cyclohexane (CH2)6 and dissimilar to aromatic D6h-symmetric benzene

We measured the terahertz spectra of five powdered vitamins, nicotinamide, nicotinic acid, ascorbic acid, pyridoxine hydrochloride, and biotin, to investigate intermolecular hydrogen bonding. These vitamins have various weak to moderate hydrogen bond
