 Abstract: The astrochemically relevant molecule 1,2-propanediol was investigated at room temperature between 75 and 110 GHz with the aims of providing accurate global rotational constants for its numerous conformers and vibrationally excited states. This was performed with our segmented chirped-pulse millimeter-wave spectrometer. In the spectrum, six previously observed conformers were assigned and treated in global fits, and three vibrationally excited states of the molecule were identified and assigned. The provided transition frequencies of the ground states and vibrationally excited states will aid in the astronomical detection of 1,2-propanediol, specifically in the Atacama Large Millimeter/submillimeter Array Band 3 regime as it overlaps with the frequency range of our spectrometer.
