N2 - Dimers of carbon disulfide (CS2) molecules embedded in helium nanodroplets are aligned using a moderately intense, 160-ps, nonresonant, circularly polarized laser pulse. It is shown that the intermolecular carbon-carbon (C-C) axis aligns along the axis perpendicular to the polarization plane of the alignment laser pulse. The degree of alignment, quantified by (cos2θ2D), is determined from the emission directions of recoiling CS2+ fragment ions, created when an intense 40-fs probe laser pulse doubly ionizes the dimers. Here, θ2D is the projection of the angle between the C-C axis on the two-dimensional (2D) ion detector and the normal to the polarization plane. (cos2θ2D) is measured as a function of the alignment laser intensity and the results agree well with (cos2θ2D) calculated for gas-phase CS2 dimers with a rotational temperature of 0.4 K.
