Abstract
The far‐infrared spectrum of trimethylene oxide has been investigated with high resolution and accuracy. A good agreement between the observed and the calculated origins of the ring‐puckering vibration bands was achieved with the potential function V(ξ) = 60 (−0.3235ξ2 + 0.1010ξ4 + 1.45 × 10−4 ξ6) cm−1 in the harmonic oscillator representation.Keywords
