We have investigated the grain alignment and dust properties towards thedirection of the cluster NGC 2345 using the multi-band optical polarimetricobservations. For the majority of the stars, the observed polarization is foundto be due to the interstellar medium with average values of maximumpolarization and wavelength corresponding to it as 1.55% and 0.58 $\mu m$,respectively. This reveals a similar size distribution of dust grains to thatin the general interstellar medium in the direction of NGC 2345. Alteration ofdust properties near the distance of 1.2 kpc towards the direction of NGC 2345has been noticed. The dust grains located beyond this distance are found to bealigned with the Galactic magnetic field, whereas a dispersion in orientationof the dust grains lying in the foreground of this distance is found.Polarizing efficiency of grains in this direction is found to be close to theaverage efficiency for our Galaxy. The decreased grain size along with theincreased polarizing efficiency towards the core region of the clusterindicates the local radiation field is higher within the cluster which isresponsible for the increased alignment efficiency of small grains. Thewavelength of maximum polarization (associated with the average size of alignedgrains) is also found to increase with extinction and reduces with the increasein polarizing efficiency, which can be explained by the radiative torquealignment mechanism.
