Microwave spectrum and conformation of 6-thiabicyclo[3.1.0]hexane

摘要: Abstract The microwave spectrum of 6-thiabicyclo[3.1.0]hexane (cyclopentene sulfide) has been measured in the region 26,500-40,000 MHz. experimental data are consistent with a single stable conformation. Furthermore, these can only be satisfactorily explained by assuming that this conformation is boat form. Rotational constants were obtained, both for ground state and two excited vibrational states, while centrifugal distortion coefficients obtained one state. rotational found A0 = 5026.243 ± 0.003 MHz, B0 2833.813 C0 2411.679 0.03 For molecule, electric dipole moment components to ∥μa∥ 1.800 0.012 D ∥μc∥ 1.155 0.024 D, yielding total μ 2.139 0.027 D.
