Far‐Infrared Spectra and Structure of Small Ring Compounds. VIII. Pseudorotation in 1,3‐Dioxolane

摘要: The infrared and Raman spectra of 1,3‐dioxolane have been examined from 800–33 cm−1. A series Q branches in the spectral region 33–100 cm−1 has treated on basis pseudorotation. was also observed 200–400 assigned to hot band transitions arising excited states pseudorotational levels. mid‐infrared shows considerable structure, but complexity due overlapping fundamentals precludes their unique assignment. spectroscopically derived parameter mq02 found be 7.4 × 10−40g·cm2 which agrees well with value for corresponding quantity tetrahydrofuran molecule.
