The purpose of the present program has been to have (1) collaborations on selected subjects of molecular science, (2) information exchange seminars, and to discuss (3) a possibility of establishing a collaborative center on molecular science and further development of collaboration between two countries. In 1995 Japanese members visited various educational, research, and government institutions in Czech Republics and discussed the above matters. In 1997 Czech counter partners visited IMS and had an information exchange seminar. Throughout two years we had conducted research by either exchange of persons or of materials and studied on 1) Theoretical and experimental studies on reaction dynamics, 2) Spectroscopic studies on biologically important molecules, 3) Time-resolved studies on molecular dynamics, and 4) Developments on functional molecular materials.Some of the hi-lights of the research program are (a) mechanistic clarification of the proton transfer and hydrogen abstraction in an ion-molecular reaction of acetonitril ion and neutral molecule, (b) theoretical identification of new interesting resonance structure in the collision reaction between electron in HI or DI molecule. (c) the intramolecular energy transfer of some bi-fiuoropher compound has been studied and significant excitation-wavelength dependence was found by the subpicosecond time-resolved spectroscopy, and (d) the mechanism of the photoconductivity of alternatively stacking molecular materials containing tetrathiafulvalene and p-chloranil as an electron acceptor has been clarified.

本计划的目的是(1)在分子科学的选定主题上进行合作，(2)信息交流研讨会，并讨论(3)建立分子科学合作中心和进一步发展两国合作的可能性。1995年，日本成员访问了捷克共和国的各种教育、研究和政府机构，并讨论了上述问题。1997年，捷克的柜台合作伙伴访问了IMS并举行了一次信息交流研讨会。两年来，我们进行了人员交换和材料交换的研究，主要包括：1)反应动力学的理论和实验研究；2)生物学重要分子的光谱研究；3)分子动力学的时间分辨研究；4)功能分子材料的研究进展。本研究计划的亮点是：(1)阐明了乙腈离子与中性分子离子-分子反应中质子转移和吸氢的机理；(2)从理论上确定了HI或DI分子中电子碰撞反应中新的有趣的共振结构。(c)研究了某些双荧光化合物的分子内能量转移，并通过亚皮秒时间分辨光谱发现了显著的激发波长依赖性；(d)阐明了以四硫代戊烯和对氯胺为电子受体的交替堆积分子材料的光导机制。
