Abstract
The present invention relates to a method for characterizing a polyacrylonitrile-based fiber, the method having a reduced error. In a spectroscopic analysis method for a polyacrylonitrile-based fiber according to the present invention, a contact degree between an inspection target and an attenuated total reflection crystal is predicted through Equation 2 and is applied to Equation 1 to correct a spectrum peak height, and thus, the peak height of the infrared spectroscopy spectrum may be measured with repeatability.
