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, τ_aaaa = -(7.64 ± 0.46) × 10^-5, τ_bbbb = -(2.076 ± 0.016) × 10^-6, τ_cccc = -(9.29 ± 0.12) × 10^-7, T₁ = (4.89 ± 0.20) × 10^-6, and T₂ = -(1.281 ± 0.016) × 10^-6cm^-1.
