Abstract 129I Mössbauer measurements have been performed on unidirectionally stretched iodinedoped polyvinyl alcohol(PVA) films which are widely used as optical polarizers. In the films iodine is observed to be in the form of I−, I 3 − , and I 5 − and the stretch of the films increases the abundance of the polyiodides, I 3 − and I 5 − . In the stretched PVA films, it has become clear that the linear polyiodides lie parallel to the stretching direction.
