## Description

 Title: Time-domain terahertz spectroscopy(0.3 - 7.5 THz) of molecular ices of simple alcohols Author(s): McGuire, Brett A. Contributor(s): Blake, Geoffrey; Carroll, Brandon; Finneran, Ian; de Vries, Xander; Allodi, Marco A.; Ioppolo, Sergio Subject(s): Astronomy Abstract: We have recently constructed a time-domain TeraHertz (THz) spectrometer for the study of molecular ices in the far-infrared. Here, we present the results of a study of amorphous and crystalline ices of simple alcohols from methanol (CH$_3$OH) through butanol (CH$_3$(CH$_2$)$_3$OH) in the region of 0.3 - 7.5 THz. We examine the effects of the length and degree of branching of the carbon chain on the observed spectra arising from the bulk, large-amplitude motions which are prominent in this spectral region. We also discuss these results in an astrochemical context: the application of these spectra to astronomical observations of interstellar ices with Herschel PACS/SPIRE and SOFIA.
