<Abstract:> Geometries and potential energies for reactants of “H-Cl-Cl” around the transition state in the reaction of H + Cl2 → HCl + Cl were calculated. The reactant on the transition state was formed at incident angle of 180°. This reactant was supported by the method of the intrinsic reaction coordinate (IRC). We produced a movie, which displays CGs of potential energy surfaces in 2-D and 3-D for reactants on the way of the reaction. The reaction profile with potential energy and structures of the reactants are also displayed. The profile was synchronized with the structures. The CG movie was tried, and it was improved through the application to student’s learning on the Web. It was effective for students to acquire images of the reaction from the standpoint of its potential energy and molecular structure.

<Abstract:> 3Dプリンタで分子モデルを作成するためにSTLファイルを創出できるCADを探したが見つけることができなかったので,分子モデリングソフトで分子デー タ(原子の位置x,y,zデータ)を作成し,それをSTLファイルに変換できるOpenSCAD言語でプログラミングすることで分子モデルの3D プリンタ用ファイルを作成してきた.その一連の作業を分子モデリングソフトWinmostar (V6.003)で実現したことを報告する.これによって,OpenSCAD言語を理解することなく,分子モデルの3Dプリンタ用ファイルを作成すること ができる.
