Vibrational Satellites and Pseudorotation in 2-Methyl-1,3-dioxolane

Resumo

Vibrational satellites caused by pseudorotation are identified in the microwave spectrum of 2-methyl-1,3-dioxolane. The rotational constants of the satellites are determined up to state v = 6. Splittings between lower pseudorotational energy levels are determined by measuring the relative intensities of rotational transitions. An attempt is made to determine the form of the pseudorotation function of the molecule using the obtained data.
