摘要：

The low frequency Raman spectra of even-numbered paraffins between C22H46 and C36H74 have been recorded over a range of temperatures up to their melting points. Particular emphasis was placed on temperatures just below the cyrstalline melting points. The structure changes in this temperature range and the spectral effects are explained. The lattice packing in the crystals was found to depend on the thermal history of the sample during its crystallization. © 1990.
