Nuclear magnetic resonance study of molecular motion in the clathrate hydrates of cyclopropane and acetone |
| abstract |
A proton magnetic resonance study of the clathrate hydrates of cyclopropane and acetone has been carried out to examine the nature and extent of molecular motion of the enclathrated ''guest molecules'' and their interaction with the deuterated ''host'' lattices. ^1H magnetic resonance spectra of the cyclopropane hydrate reveal highly restricted rotation of the cyclopropane guest up to 240^o K, and then a free rotation about the C"3-axis of symmetry at high temperatures both for type I and type II clathrate hydrates. The results of proton magnetic resonance studies of acetone deuterate indicate the usual phenomenon of CH"3-group rotation even at 77^o K, and a self diffusion of acetone at 172^o K. The barrier hindering the diffusion of acetone has been calculated from line width-temperature data to be 3.95 kcal mole^-^1. |

The results of proton magnetic resonance studies of acetone deuterate indicate the usual phenomenon of CH"3-group rotation even at 77^o K, and a self diffusion of acetone at 172^o K. The barrier hindering the diffusion of acetone has been calculated from line width-temperature data to be 3.95 kcal mole^-^1.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="f">Elsevier Journal Backfiles on ScienceDirect 1907 - 2002</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Khanzada, A.W.K.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mcdowell, C.A.</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">in</subfield><subfield code="t">Journal of Molecular Structure</subfield><subfield code="d">Amsterdam : Elsevier</subfield><subfield code="g">7(1971), 1-2, Seite 241-251</subfield><subfield code="w">(DE-627)NLEJ174352263</subfield><subfield code="w">(DE-600)1491504-2</subfield><subfield code="x">0022-2860</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:7</subfield><subfield code="g">year:1971</subfield><subfield code="g">number:1-2</subfield><subfield code="g">pages:241-251</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://linkinghub.elsevier.com/retrieve/pii/0022-2860(71)90024-X</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_H</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-SDJ</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">7</subfield><subfield code="j">1971</subfield><subfield code="e">1-2</subfield><subfield code="h">241-251</subfield></datafield></record></collection>
