Spin-lattice relaxation in normal alkanes at elevated pressures
A high pressure, variable temperature NMR probe for low signal to noise relaxation time and self-diffusion coefficient measurements was constructed and tested. The probe has a high pressure limit of 10,000 psia and a current ...
Spin lattice relaxation in pure and mixed alkanes and their correlation with thermodynamic and macroscopic transport properties
Spin-lattice, T$\sb1$, and spin-spin, T$\sb2$, relaxation times of the alkanes from n-pentane to n-hexadecane were measured at 25$\sp\circ$C. The T$\sb1$ values agree well with those of previous investigators. The values ...
