摘要：

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 CH2I2, O-2 and Ar. Doppler limited measurements were made in the frequency ranges 220-320, 580-680 and 970-1080 GHz. 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-a(max) = 14 of the a-dipole spectrum. (C) 2014 Elsevier Inc.
