摘要用分子束傅里叶变换微波光谱仪研究了1，2，3-三氟苯在5~13 GHz频率范围内的微波光谱。旋转和四次离心变形常数分别为A=2319.5995(2)MHz，B=1757.8298(2)MHz，C=999.9370(1)MHz，ΔJ=0.061(3)kHz，ΔJK=0.010(7)kHz，ΔK=0.062(7)kHz，δJ=0.023(1)kHz，δK=0.089(4)kHz。偶极矩为μb=3.00(4)D。
Abstract The microwave spectrum of 1,2,3-trifluorobenzene was studied in the frequency region between 5 and 13 GHz using a molecular beam Fourier transform microwave spectrometer. The rotational and quartic centrifugal distortion constants were found to be A = 2319.5995(2) MHz, B = 1757.8298(2) MHz, C = 999.9370(1) MHz, Δ J = 0.061(3) kHz, Δ JK = 0.010(7) kHz, Δ K = 0.062(7) kHz, δ J = 0.023(1) kHz, and δ K = 0.089(4) kHz. The dipole moment was obtained to be μ b = 3.00(4) D.
