摘要:The Microwave Spectra Of Four Isotopic Species Of Gauche-1,2-Difluoroethane Have Been Observed. Having Combined The Rotational Constants Obtained With Those Of The Normal Species,All The Structural Parameters Have Been Determined As Follows; R(C-c)=1.493(8) å,R(C-f) =1.390(3) å,R(C-hg)=1.099(2) å,R(C-ht)=1.093(5) å,∠ccf=110.6(5)°,∠cchg=108.4(6)°,∠ccht=111.3(6)°,∠hch=109.1(5)°,∠fchg=109.6(3)°,∠fcht=107.8(6)°,And Fccf (Dihedral Angle)=71.0(3)°. The Spectra Of Normal Species In The Excited Torsional States Have Also Been Observed Up To Vt=4,And The Results Of The Analysis Indicate That The Gauche-Gauche Barrier Should Be Higher Than The Value,468.6 Cm−1,Reported By The Analysis Of Vibrational Spectra.
