Shunnosuke Okino   Tomohisa Takaya   Koichi Iwata   
CHEMISTRY LETTERS   44(8) 1059-1061   2015年8月   [査読有り]
The energies of low-lying singlet excited states of oligothiophenes, xT's (x = 3 to 8), and polythiophene are determined using femtosecond time-resolved near-infrared spectroscopy. The energies are linearly correlated with the reciprocal number of...

ANALYST   140(6) 1847-1851   2015年   [査読有り]
Raman imaging is one of the very informative methods for the characterization of chemically and structurally heterogeneous materials without employing specific molecular labels. Multifocus Raman imaging is one of the fast-imaging alternatives to t...
 
Yuki Nojima   Koichi Iwata   
JOURNAL OF PHYSICAL CHEMISTRY B   118(29) 8631-8641   2014年7月   [査読有り]
A number of biochemical reactions proceed inside biomembranes. Because the rate of a chemical reaction is influenced by chemical properties of the reaction field, it is important to examine the chemical properties inside the biomembranes, or lipid...
 
Tomohisa Takaya   Koichi Iwata   
JOURNAL OF PHYSICAL CHEMISTRY A   118(23) 4071-4078   2014年6月   [査読有り]
Carotenoids have two major low-lying excited states, the second lowest (S-2 (1B(u)(+))) and the lowest (S-1 (2A(g)(-))) excited singlet states, both of which are suggested to be involved in the energy transfer processes in light-harvesting complex...
 
Koichi Iwata   
JOURNAL OF RAMAN SPECTROSCOPY   39(11) 1512-1517   2008年11月   [査読有り]
Ultrafast bimolecular radical reaction proceeds between photoexcited p-terphenyl and carbon tetrachloride. The lifetime of the first excited singlet (Si) state of p-terphenyl in carbon tetrachloride measured with picosecond time-resolved fluoresce...

Yuki Nojima   Koichi Iwata   
CHEMISTRY-AN ASIAN JOURNAL   6(7) 1817-1824   2011年7月   
Viscosity inside the lipid bilayer of egg-PC (egg yolk phosphatidylcholine) liposome with a diameter of 100 nm is examined with picosecond time-resolved fluorescence spectroscopy. The viscosity is estimated independently from the photoisomerizatio...
 
Sandor Kunsagi-Mate   Zsolt Csok   Koichi Iwata   Erzsebet Szasz   Laszlo Kollar   
JOURNAL OF PHYSICAL CHEMISTRY B   115(13) 3339-3343   2011年4月   
The interaction of phenol guest molecules with 2-methylresorcinarene and its methylene-bridged cavitand derivative has been investigated in methanol. The host molecules were selected according to the flexibility of their cavities by varying the co...
 
Nobuyuki Asami   Tomohisa Takaya   Soshi Yabumoto   Shinsuke Shigeto   Hiro-o Hamaguchi   Koichi Iwata   
JOURNAL OF PHYSICAL CHEMISTRY A   114(22) 6351-6355   2010年6月   
Transient absorption spectra of 9,9'-bianthryl (BA) in heptane, in acetonitrile, and in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (bmimTf(2)N) are observed with a nanosecond time-resolved near-IR absorption spectrometer for the...
 
Sandor Kunsagi-Mate   Koichi Iwata   
CHEMICAL PHYSICS LETTERS   473(4-6) 284-287   2009年5月   
The formation of the solvatation shell of anthracene molecule was investigated in binary mixtures of protic alcoholic solvents by solvent-relaxation measurements, anisotropy decay studies and quantum-chemical modeling. Results show significant cha...
 
Motohiro Banno   Koichi Iwata   Hiro-o Hamaguchi   
JOURNAL OF PHYSICAL CHEMISTRY A   113(6) 1007-1011   2009年2月   
The rate of vibrational energy relaxation (VER) is a valuable probe of microscopic intermolecular interaction. In the present article, the VER rate of the T-1u CO stretch of W(CO)(6) is measured in binary solutions composed of ail alkane (hexane, ...
