Experiments are reported which describe the trapping of the unstable fruns conformer of 1.2difluoroethane in argon matrices. Assignments of the infrared spectra of the guuche and rrans conformers are given. The latter is shown to have a 600 c-al/ma1 higher free enthalpy. 1,2difluoroethane (DFE) may
## Abstract The ^1^__J__~CH~ coupling constants in conformationally constrained sulfoxides, bissulfoxides, sulfoxide‐sulfones, and sulfilimines derived from 2‐benzylidene‐1,3‐dithiane and 2‐(2,2‐dimethylpropylidene)‐1,3‐dithiolane were measured by means of HMQC and HSQC NMR experiments and the Per
