Abstract

The pure rotational spectrum of CH2F2 was recorded in the 20-100 cm-1 spectral range and analyzed to obtain rotation and centrifugal distortion constants. Analysis of the data yielded rotation constants: A = 1.6392173 ± 0.0000015, B = 0.3537342 ± 0.00000033, C = 0.3085387 ± 0.00000027, τaaaa = -(7.64 ± 0.46) × 10-5, τbbbb = -(2.076 ± 0.016) × 10-6, τcccc = -(9.29 ± 0.12) × 10-7, T1 = (4.89 ± 0.20) × 10-6, and T2 = -(1.281 ± 0.016) × 10-6cm-1.
