Mutual viscosity and NMR spin-lattice relaxation time in some polar molecules

摘要

Present communication reports the experimental values of the NMR spin-lattice relaxation time (T ₁) of 10 polar molecules and mutual viscosity () of 2-fluorobenzaldehyde, 3-fluorobenzaldehyde and 4-fluorobenzaldehyde. The experimental values of T ₁ have been correlated with the calculated value of T ₁ obtained using different equations for the dielectric relaxation time (). It is concluded from this comparative study that the Murty equation is a useful representation of the dielectric relaxation phenomenon. It is also concluded that the mutual viscosity () is a substitute for the resistance to the rotation of the individual solute molecule.View full textDownload full textKeywordsNMR spin-lattice relaxation time (T 1), mutual viscosity (η 12), dielectric relaxation time (τ)Related var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00319104.2011.646442
