Equatorial and axial hydrogens in heterocyclic six-membered rings: the rotational spectrum of piperazine
TL;DR: In this article, the rotational spectrum of piperazine has been investigated by free jet absorption millimeter wave spectroscopy, and the spectrum of the polar conformer with axial-equatorial orientations of the two amino hydrogens was only observed.

Centrifugal Distortion Effects in The Microwave Spectrum of Thiomorpholine
TL;DR: In this article, a first order distortion analysis was carried out on the equatorial form of normal thiomorpholine (CH2-CH 2-S-CH2 -S, CH2-NH) and the obtained frequencies combined with the low J transitions were used to determine the Watson's distortion constants.

Microwave spectrum of morpholine
J. J. Sloan,R. Kewley +1 more
TL;DR: In this paper, the microwave spectra of morpholine and N-deuteromorpholine have been investigated within the 8 to 40 GHz region, and strong a-type spectra which are due to the chair conformer with an equatorial imino group were recorded.
