STRUCTURAL FORMULA DISPLAY SYSTEM, STRUCTURAL FORMULA DISPLAY METHOD, AND STRUCTURAL FORMULA DISPLAY PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a structural formula display method, capable of displaying a structural formula in a manner easy for a user to know the structure of a chemical composition even if the arrangement of a character string in the structural formula is changed. PSOLUTION: A character string dividing means 32 divides a targeted character string into a plurality of groups at each bonding site on a main chain. The character string dividing means 32 adds starting/ending symbols to the targeted character string, inserts a delimiter between adjacent characters, changes a notation related to oxo acids, reconstructs an atomic symbol consisting of two characters, changes a notation regarding a subscript or superscript, links hydrogen to another element, reconstructs a set of side chains, reconstructs a character string consisting of one group, reconstructs a back-end group, reconstructs a double bond in a group, and removes the starting/ending symbols. A character string reversing means 34 reverses the alignment of the groups. PCOPYRIGHT: (C)2008,JPO&INPIT
