• Present communication reports on the experimental values of NMR spin–lattice relaxation time ($T_{1}$) of 3-hydroxy, 4-methoxy benzaldehyde, 4-hydroxy, 3-methoxy benzaldehyde, $o$-nitrobenzaldehyde, $o$-hydroxy benzaldehyde and $ p$-chlorobenzaldehyde and Mutual viscosity ($\eta_{12}$) of $o$-chlorobenzaldehyde, $m$-chlorobenzaldehyde and $ p$-chlorobenzaldehyde. The experimental values of $T_{1}$ have been correlated with the calculated values of $T_{1}$ obtained using various equations of the dielectric relaxation time ($\tau$). It has been concluded that the equations of Writz and Murty are better representations of the dielectric relaxation phenomenon. From the correlation of $\tau$ and $\eta_{1}$ it has been found that the coefficient of mutual viscosity ($\eta_{12}$) is a better representation of the hindrance to the rotation of the individual solute molecules.
