Journal ArticleDOI
Excited-state intramolecular proton transfer and charge transfer in 2-(2′-hydroxyphenyl)benzimidazole crystals studied by polymorphs-selected electronic spectroscopy
Hayato Konoshima,Saori Nagao,Issui Kiyota,Kiichi Amimoto,Norifumi Yamamoto,Masahiko Sekine,Munetaka Nakata,Kazuki Furukawa,Hiroshi Sekiya +8 more
TL;DR: Crystal structures of polymorphs of 2-(2'-hydroxyphenyl)benzimidazole (HPBI), Forms α and β, are analyzed by X-ray crystallography and it is found that the electronic spectra of the two crystal forms are significantly different from each other.
Journal ArticleDOI
Infrared photodissociation spectroscopy of [Aniline-(Water)n]+ (n = 1-8): Structural change from branched and cyclic to proton-transferred forms
Yoshiya Inokuchi,Kazuhiko Ohashi,Yoshiki Honkawa,Norifumi Yamamoto,Hiroshi Sekiya,Nobuyuki Nishi +5 more
TL;DR: In this article, the infrared photodissociation spectra of [aniline−(H2O)n]- (n = 1−8) are measured in the 2700−3800 cm-1 region.
Journal Article
Ferryl–Oxo Species Produced from Fenton’s Reagent via a Two-Step Pathway: Minimum Free-Energy Path Analysis B
TL;DR: In this paper, the authors determined minimum free-energy paths (MFEPs) from Fenton's reagent to possible oxidizing agents such as hydroxyl radicals and ferryl-oxo species by combining ab initio molecular dynamics simulations and an MFEP search method.
Journal ArticleDOI
Mechanisms of Aggregation-Induced Emission and Photo/Thermal E/Z Isomerization of a Cyanostilbene Derivative: Theoretical Insights
TL;DR: In this article, aggregation-induced emission (AIE) of a cyanostilbene derivative, called 1-cyano-1,2-bis-(4′-methylbiphenyl)ethylene (CN-MBE), was investigated using molecular simulations.
Journal ArticleDOI
Electronic and vibrational spectra of aniline–benzene hetero-dimer and aniline homo-dimer ions
Kazuhiko Ohashi,Yoshiya Inokuchi,Hironobu Izutsu,Kazuyuki Hino,Norifumi Yamamoto,Nobuyuki Nishi,Hiroshi Sekiya +6 more
TL;DR: In this paper, the structure of (aniline-benzene) + was investigated by electronic spectroscopy in the near-infrared region and vibrational spectrograms in the NH stretching region.
