The resonance Raman spectrum of crystalline poly[bis( p ‐toluene sulfonate) of 2,4‐hexadiyne‐1,6‐diol] has been studied as a function of applied pressure to 50 kbar. The Raman bands are observed to shift to higher frequency and change in relative intensity. The origins of these effects are discussed. One of the Raman bands is observed to split into two bands of approximately equal intensity at high pressure. This effect is attributed to correlation field splitting within the unit cell and is possibly the first such observation in a conjugated polymer.
