摘要纤维是刑事案件中比较常见的物证和线索,在物证中被广泛研究。利用衰减全反射红外光谱(ATR)对日常比较常见纤维进行了红外光谱测定和详尽的红外光谱分析,依据红外光谱图中吸收峰的不同将纤维样品加以鉴别。此方法不破坏检材、速度快、需要样品量极少、重现性好,为纤维物证分析鉴定提供了新的研究方法,可用于鉴定犯罪现场的纤维。

Abstract: Fiber can provide strong clues and supportive evidence for relevant cases of criminal offence,having been extensively studied in forensic investigations.This experiment tested different kinds of fiber by FTIR-ATR method.According to different absorption peaks of infrared spectra, we may differentiate fbers.The method is a nondestructive analytical technique, which needs a small amount of sample and rapid testing, has good repeatability, therefore can be used to characterize fibers from crime scene.

Key words: trace fiber evidence comparative analysis infrared spectroscopy spectral analysis
