A FAR INFRARED SYNCHROTRON-BASED INVESTIGATION OF 3-OXETANONE

Author Institution: Department of Chemistry, University of Manitoba, Winnipeg MB R3T 2N2 CanadaThe four membered ester ring 3-oxetanone is a precursor for adding oxetane subunits into pharmaceuticals which then block metabolically exposed sites in the bioactive molecule without increasing its lipophilicity. The high resolution (0.00096 cm$\cm^{-1}$) rovibrational spectrum of 3-oxetanone was recorded for the first time using far infrared radiation from the Canadian Light Source (CLS) synchrotron facility coupled to a Bruker IFS125HR FTIR spectrometer. A total of six rotationally-resolved vibrational bands were observed between 360 and 1150 cm$\cm^{-1}$ at room temperature. The assignment of the dense spectrum is currently underway and the progress will be discussed in this talk
