Research output: Contribution to journalArticlepeer-review


Rotationally-resolved spectra of the ν16 band of 1,3,5-trioxane, centered near 1177 cm-1, have been obtained via cavity ringdown spectroscopy using a continuous-wave external-cavity quantum cascade laser and a slit expansion nozzle. 219 transitions were identified and fitted to determine the excited state rotational constants for this band. In addition to fundamental interest, these data could facilitate spectroscopic detection of trioxane in cometary comae as a tracer for polyoxymethylene.
