Interaction of a practical fluoran-based black color former with possible color developers, various acids and magnesium ions, in acetonitrile

Autor: Tadaharu Ueda, Sumio Tokita, Masashi Hojo, Akihiko Inoue

Publikováno v: Journal of Molecular Liquids. 148:109-113

For the purpose of improving the visible method of γ-rays detection, detailed conditions with various acids have been examined for the color development of a fluoran-based black color former in acetonitrile. It is suggested that the protons (H + ),

Changes of Electron Donation by Substituents for SN Ylides Obtained by ab initio Calculations

Autor: Shun-ichi Mitomo, Manabu Seno, Sumio Tokita

Publikováno v: Journal of Photopolymer Science and Technology. 19:9-14

Relationships between the HOMO energy and σ(p) in ylides 1-14 have been studied. Linear relationships between the HOMO energies obtained by HF/3-21G[*] and 6-31G*, BLYP/6-31G*, and B3LYP/6-31G* methods and the substituent constant (σ(p)) were found

A Three-Dimensional Representation of Born's Probability Densities of Hydrogen Atomic Orbitals in Glass Blocks

Autor: Sumio Tokita, Teruo Nagao, Nakako Tokita

Publikováno v: Journal of Computer Chemistry, Japan. 5:153-158

We report here a novel method of visualization to record Born's probability densities in glass blocks by the use of a recently developed three-dimensional laser technique. Conventional visualization methods cannot simultaneously show all the characte
