Raman and infrared spectra of solid 2,3-dimethylbutyne

The infrared and Raman spectra of polycrystalline (CH3)3CCCH were recorded at 77 and 10 K, respectively. Crystal splittings were observed for some of the fundamentals and possible crystal structures are discussed. Anomalous band shifts between the liquid and solid state spectra were noted for butyne...

Description
Summary:The infrared and Raman spectra of polycrystalline (CH3)3CCCH were recorded at 77 and 10 K, respectively. Crystal splittings were observed for some of the fundamentals and possible crystal structures are discussed. Anomalous band shifts between the liquid and solid state spectra were noted for butyne ≡CH modes, indicating that a strong intermolecular interaction involving the butyne CH group occurs in the crystalline state. The temperature dependence of the Raman spectra was measured for some prominent fundamental bands. No phase changes were detected. In the solid‐state Raman spectrum, bands attributable to both A2 and E methyl torsions were observed. © 1998 John Wiley & Sons, Ltd.
