Isomers Communication

Japanese Edition  (HP2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011)


English Edition  (2011)


Isomers is the name of the organization of the alumni who graduated in 1958 from Industrial Chemistry Department of Kyoto University, Kyoto, Japan. The purpose of Isomers Communication is to publish essays and other articles authored by the members.  The articles in the volumes prior to 2011 are mostly written in Japanese.  However, in order to invite the visitors who do not read Japanese language, we decided to open this English edition that posts the articles written in English, some of which are translation of the articles written in the past volumes. 


The pace of posting articles on this edition is expected to be slow (perhaps one or two articles a month), but our effort will continue. We expect you to visit this page once in a while.  If you have any comments, please do not hesitate to write to
