The σ-stark effect of rotational transitions : Part II: The microwave spectrum of methyl alcohol

Abstract

The method described in Part I is applied to absorption lines of methyl alcohol in the microwave region. Recorded ΔM = ± 1 Stark patterns of absorption lines with linear Stark effect are compared with calculated patterns.

The ΔM = ± 1 Stark patterns of 7 absorption lines with second order Stark effect are investigated. A method is described for a determination of J (the lower constant of overall rotation involved in the transition) using the Stark effect constants derived from ΔM = ± 1 and ΔM = 0 patterns.
