The millimeter- and submillimeter-wave spectrum of methylene fluoride-d(2) (CD(2)F(2)) has been observed in the region between 200 and 415 GHz. The spectrum was recorded using a frequency-modulated millimeter- and submillimeter-wave spectrometer. More than 400 rotational transitions up to J </= 60 and K(a) </= 21 in the ground state and more than 200 rotational transitions up to J </= 48 and K(a) </= 9 in the v(4) = 1 vibrational state have been assigned. The lines assigned are simultaneously least-squares fitted along with the microwave data in the Watson's A- and S-reduced Hamiltonian. Improved values have been obtained for the rotational constants and quartic centrifugal distortion constants, including for the first time, sextic distortion constants of the ground state as well as the v(4) = 1 state.

在200至415吉赫兹的频段内观测到了二氟甲烷-d₂（CD₂F₂）的毫米波和亚毫米波光谱。该光谱是使用调频毫米波和亚毫米波光谱仪记录的。已确定了基态下高达J≤60且Kₐ≤21的400多个转动跃迁以及v₄ = 1振动态下高达J≤48且Kₐ≤9的200多个转动跃迁。所确定的谱线与微波数据一起在沃森A-和S-简化哈密顿量中进行了最小二乘拟合。获得了转动常数和四次离心畸变常数的改进值，首次包括了基态以及v₄ = 1态的六次畸变常数。版权所有1999年学术出版社。
