Infra-Red and Raman Spectra of Polyatomic Molecules IX. Dimethyl Acetylene, C4H6

The infra-red absorption of gaseous C4H6 has been measured from 2 to 24μ, and the Raman spectrum of the liquid studied. Analysis of the data permits the determination of all the fundamental frequencies of the molecule. The frequencies are fitted closely with a modified valence-force potential functi...

Zusammenfassung:The infra-red absorption of gaseous C4H6 has been measured from 2 to 24μ, and the Raman spectrum of the liquid studied. Analysis of the data permits the determination of all the fundamental frequencies of the molecule. The frequencies are fitted closely with a modified valence-force potential function in which the methyl-group force constants are those previously determined for ethane.
