Abstract

The rotational spectrum of the chiral mono-deuterated oxirane c-C$_2$H$_3$DO, an isotopomer of oxirane (ethylenoxide), of which the normal isotopomer has already been detected in interstellar clouds, was measured in the ranges 78 to 108 GHz and 25 to 70 cm$^{-1}$. Thus one can expect that c-C$_2$H$_3$DO will be detectable in space in the future given the current accurate laboratory data.c-C$_2$H$_3$DO is also of interest as a simple prototypical molecule for isotopic chirality and parity violation.footnote{M.

A total of 119 transitions have been newly assigned in the GHz range (extended to 119 GHz) up to J=18 and 900 transitions in the THz region at most to J=70. The analyses of the rotational spectra shall be discussed in detail in relation to their astrophysical importance.
