摘要

C-H symmetric stretching vibrational frequencies of CH4, C(2)H(4)and C(2)H(6)molecules encapsulated in 5(12), 5(12)6(2)and 5(12)6(4)cages of structures I (sI) and II (sII) clathrate hydrates measured by Raman spectroscopy in the temperature range of 93-183 K was analysed. The slopes of the symmetric stretch vibrational frequencies under changing temperatures (Delta v/Delta T) for CH4, C(2)H(4)and C(2)H(6)molecules encapsulated in sII 5(12)6(4)cages were smaller than those for molecules in sI 5(12)6(2)cages, although sI 5(12)6(2)cages are smaller than sII 5(12)6(4)cages. We compared the results of Delta v/Delta Tin this study with the geometrical properties of each host water cage, and these comparisons suggest that the geometry of host water cages affects Delta v/Delta T.
