Abstract
Z .This Letter presents the high-resolution C 1s near-edge X-ray absorption fine structure NEXAFS spectra of hydro-
genated and deuterated polystyrene. The differences between these spectra provide unambiguous evidence for the presence

of a significant vibronic contribution to the shape and structure of the C 1s C­H TM1p transition in polystyrene.C- C
