Abstract:1,3,5-trioxane is the simplest cyclic form of polyoxymethylene (POM), a class of formaldehyde polymers that has been proposed as the origin of distributed formaldehyde formation in comet comae and a potential source of formaldehyde in prebiotic chemistry. Although claimed POM detections have since been proven to be inconclusive, laboratory simulations of cometary conditions have yielded trioxane and other POMsfootnote{Cottin, H., Bホnilan, Y., Gazeau, M-C., and Raulin, F. Origin of Cometary Extended Sources from Degradation of Refractory Organics on Grains: Polyoxymethylene as Formaldehyde Parent Molecule. textit{Icarus} textbf{167} (2004), 397-416.}. While the microwave spectrum of 1,3,5-trioxane has been studied extensivelyfootnote{Oka, T., Tsuchiya, K., Iwata, S., and Morino, Y. Microwave Spectrum of s-Trioxane. textit{Bull. Chem. Soc. Jpn.} textbf{37} (1964), 4-7.}, to date only one rotationally-resolved ro-vibrational spectrum has been publishedfootnote{Henninot, J-F., Bolvin, H., Demaison, J., and Lemoine, B. The Infrared Spectrum of Trioxane in a Supersonic Slit Jet. textit{J. Mol. Spect.} textbf{152} (1992), 62-68.}. Here, we present our studies of the nub{16} band of gas-phase trioxane centered at 1177 wn. Trioxane was entrained in a supersonic expansion of argon and characterized by continuous-wave cavity ringdown spectroscopy using an etalon-stabilized external-cavity quantum cascade laserfootnote{Gibson, B.M. and McCall, B.J., contribution TJ08, presented at the 69$^{th}$ International Symposium on Molecular Spectroscopy, Urbana, IL, USA, 2014.}. Rotationally resolved spectra were obtained with less than 15 MHz resolution.
