When wood is carbonized, a distinctive form is observed, such as the surface turning black or cracking, but no clear appraisal method has been established, and the criteria set by individual appraisers have not been established. The current situation is that appraisal is conducted based on these individual appraisal methods. However, it is expected that the presence or absence of carbonization of the wood can be objectively determined by measuring the infrared absorption spectrum of the burned wood using a Fourier transform infrared spectrophotometer. Therefore, in this study, an experimental model was con-structed on the assumption of an actual arson case, a combustion experiment was performed on wood, which is widely used as a building material, and data on the ob-tained carbides were examined and objectively carbonized. We have devised a carbonization appraisal method. In this study, in addition to FT  IR analysis, SEM  EDX analysis and XRD analysis were also used to analyze detailed carbides. As a result, FT  IR analysis showed that objective wood can be identiˆed for carbonization. However, when heated by a high temperature ‰ame, the wood transitions to complete carbide, but when heated by a relatively low temperature ‰ame as in the experimental model implemented in this study,","PeriodicalId":14709,"journal":{"name":"Japanese Journal of Forensic Science and Technology","volume":"132 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91054993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
