Abstract

High frequency pure rotational transitions of the simplest Criegee intermediate, methylene peroxide (CH2OO), have been measured up to 1 THz. The data provide the most accurate spectroscopic parameters for the ground vibrational state. The molecule was produced in a flow cell with a DC discharge of CH$_{2}$I$_{2}$, O$_{2}$ and Ar. Doppler limited measurements were made in the frequency ranges 220-320, 580-680 and 970-1080 GHz at room temperature. A total of 211 transitions were measured and added to four transitions measured in the microwave to obtain a fit up to J$^{max}$ = 49 and K$^{max}$ = 14 of the a-dipole spectrum.
