Strong light fields are known for their capability to align molecules in free space [1]. The presence of this strong laser field also influences the dissociation dynamics of molecules. In this talk we present results on adiabatic alignment and dissociation of CH3I using an improved velocity map imaging spectrometer. Dissociation and ionization of the molecules are accomplished by using solely nanosecond lasers. With the strong field present, we observe alignment of the molecules and new channels in the dissociation of CH3I. In the future, the aligned molecules will be used to study orientational effects in reactions with ions.
