Abstract

The $c$ -type rotational structure belonging to the $n =1→ n =2$ pseudomotational transition in tetrahydrofuran (THF) has been observed in die region of 185-326 GHz. The transitions have been observed using a pulsed jet fast scan absorption $s p e c t o m e t e r a$ . The apparatus incorporates a free running backward wave oscillator (BWO) and utilizes a technique which is an extension of FASSST spectroscopy to a pulsed jet environment. A suitable model to fit the available spetroscopic data along with the assignment of the observed pseudorotational transitions is discussed, and the analysis of the experimental data combined with data obtained $p r e v i o u s l y b$ is presented.
