WebRaman and IR spectra of solutions of CHCl 3 /DMSO-d 6 and CDCl 3 /DMSO-h 6 (DMSO = dimethyl sulfoxide) solutions are presented and analyzed in terms of hydrogen-bonding interactions. In the region of the C−H stretch of CHCl 3 or the C−D stretch of CDCl 3, addition of DMSO causes a new band to appear which is broadened and red-shifted with … WebThe C-H he is drawing is not an O-chem line structure. It is the presence of a hydrogen bonded to a carbon in an sp3 sigma bond. He is determining what groups of molecules he has, but not drawing a molecular structure.
