Mössbauer spectroscopic study of the β-carotene–iodine system

Abstract

The ¹²⁹I Mössbauer effect has been applied to the β-carotene–iodine system prepared by the precipitation method. The system can be described in terms of the completely charge-transferred form, C₄₀H₅₆⁺⋯ I₃^–, where the I₃^– has a symmetrical charge distribution. The optical and electrical properties of the β-carotene–iodine system are discussed on the basis of the Mössbauer results.
