Sažetak
During spectroscopic investigations of acetylenic compounds with phenyl and trimethylsilyl terminal group(s) an unusual and hitherto unexplained phenomenon has been observed in their Raman spectra. The band that originates from the acetylenic stretching has pronounced asymmetry on the low-frequency side. The asymmetry is most probably a consequence of the unresolved hot band sequence that occurs due to the coupling between the acetylenic stretching and the linear bending. The hypothesis is based on the existence of such a sequence in gas and liquid phase spectra of halogeno substituted acetylenes and also on the experimental results that have already been obtained for DPA and PA under different conditions.
