摘要：
Cyclopropane (CH2)(3) was studied by advanced methods of NMR spectroscopy in liquid and gaseous states at 300 K. Extrapolation of gas-phase chemical shifts to the zero-density limit allowed the determinations of H-1 and C-13 absolute nuclear magnetic shieldings of an isolated cyclopropane molecule. The indirect spin-spin coupling constants were extracted from experimental spectra and compared with the calculated values reported in the literature.
