Abstract
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.Keywords
