    Study on Exciton Circlar Dichroism in Europium(III)Complexes with Chiral β-diketonato ligands

    Full text link
    In this study, the exciton circular dichroism(exciton CD) of the tris(chiral β-diketonato) europium( III) complex[ EuI(II(+)-hfbc)3]which would exhibit large chirality in sulfoxide(dmso) solution were reported and its dissolved configuration were considered in comparison with the previous related studies of chiroptical spectra in chiral EuIII complexes.  The exciton CD, fluorescence and excitation spectrum were changed as the concentration of dmso solution of[ EuI(II(+)-hfbc)3]increased. Especially, the exciton CD showed remarkable bands with large Δε(molar absorptivity) in ultraviolet region. These results indicate another EuIII complex[ EuI(II(+)-hfbc)(3 dmso)n]are generated with increasing dmso solution and it retains chiral configuration.  The ultimate goal of a series of this study is to develop measurement of Magnetochiral dichroism(MchD) in chiral lanthanide( III()LnIII) complexes. These chiroptical spectra data of[ EuI(II(+)-hfbc)3]would serve a basic data in MchD measurement and lead to investigate a relation between MchD and chiral configurations in chiral LnIII complexes.departmental bulletin pape

    Onomatopoeic Representation of Sounds

    Full text link
    音や動作を言葉で表現するには「擬音語・擬態語」を用いることはわが国では万葉の時代から行われ,その種類も豊富である。ここでは,身の回りで発生する音とその擬音語の関係を取り上げた。とくに摩擦により発生する音はあまり感じないようであるが,しっかりと我々の身の周りに深く入り込んでいる。また,官能小説,マンガ等の分野は多くの擬音語が使用されており,効果的な使用方法があることを示した。departmental bulletin pape

    Translation and Annotation of the Mathematical Books of Qin Bamboo Slips Housed at Peking University, Vol. 1

    Full text link
    The book “Suanshu( 算書)” Jiazhong( 甲種) is one of the mathematical books of Qin bamboo slips donated to Peking University in 2009. The aim of our research is to provide a complete translation and annotation of it from the iewpoint of our previous work on ancient Chinese mathematics.  This is the first article based on our research and results in which we studied the slips of Lu Jiuci toi shu(魯久次問数)『算書』甲種は2009年に北京大学に寄贈された算数関係書籍簡の一つである。我々は、我々の中国古算書研究を起点に、『算書』甲種の訳注を完成させることを目的としている。  本論文では、『算書』甲種冒頭の「魯久次問数」篇に対する訳注を与える。departmental bulletin pape
