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...

Sandor Kunsagi-Mate   Koichi Iwata   
JOURNAL OF SOLUTION CHEMISTRY   42(1) 165-171   2013年1月   
The dynamic motions of solvent molecules in the solvation shell of phenols in binary water-ethanol solutions have been examined experimentally by measuring the solvent relaxation times using phase-fluorometry. The results show that the mono-expone...
 
Nobuyuki Asami   Sohshi Yabumoto   Shinsuke Shigeto   Tomohisa Takaya   Hiro-o Hamaguchi   Koichi Iwata   
CHEMISTRY LETTERS   41(6) 654-656   2012年6月   
Nanosecond time-resolved infrared spectra of photoexcited 9,9'-bianthryl (BA) and its deuterated derivative (BA-d(18)) were recorded in acetonitrile-d(3) and cyclohexane-d(12). The charge-transfer (CT) bands observed at the 1200-1400 cm(-1) region...
 
Kyousuke Yoshida   Koichi Iwata   Yoshio Nishiyama   Yoshifumi Kimura   Hiro-o Hamaguchi   
JOURNAL OF CHEMICAL PHYSICS   136(10) 104504-1 - 104504-8   2012年3月   
Vibrational cooling rate of the first excited singlet (S1) state of trans-stilbene and bulk thermal diffusivity are measured for seven room temperature ionic liquids, C2mimTf2N, C4mimTf2N, C4mimPF6, C5mimTf2N, C6mimTf2N, C8mimTf2N, and bmpyTf2N. V...
 
Hiroko Miki   Kyousuke Yoshida   Chieko Kawate   Rintaro Shimada   Tomohisa Takaya   Koichi Iwata   Hiro-o Hamaguchi   
CHEMICAL PHYSICS LETTERS   527 27-30   2012年2月   
Picosecond time-resolved visible absorption and Raman spectra of trans-stilbene in acetonitrile have been measured. A new transient absorption band is observed at 440 nm, whose decay time constant coincides with that of the rise of the radical cat...
 
Yin Li   Zsolt Csok   Laszlo Kollar   Koichi Iwata   Erzsebet Szasz   Sandor Kunsagi-Mate   
SUPRAMOLECULAR CHEMISTRY   24(6) 374-378   2012年   
2-Methylresorcinarene and its methylene-bridged cavitand derivative as host compounds were investigated in selective complexation of alkali metal ions as guests in methanol media by photoluminescence measurements. These host molecules possess eith...
