Abstract
Dating ballpoint pen hand-writings is a hot topic in forensic science. It remains untested whether NMR spectroscopy is suitable for this task. In this study, six types of oily ballpoint pen ink were characterized by1H NMR spectroscopy. The same method was also used to measure the changes of 2-phenoxyethanol content in oily ballpoint pen hand-writings with aging. A standard curve was established based on the experimental results. It was demonstrated that, as long as the brand of the oily ballpoint pen used was known, hand-writings made within 4 months could be dated precisely. The effects of artificial aging and natural aging were compared subsequently. It was found that ten minutes in ultraviolet aging box corresponded to approximately one day of natural aging.关键词
