Abstract : A modification is made to the semiclassical adiabatic invariance method for ion-dipole and ion-quadrupole capture collisions. This modification to the adiabatic invariance method includes the effects of coupling of the rotational angular momentum of the target molecule with the orbital angular momentum of the projectile ion. The adiabatic potential energies, cross sections and rate coefficients for capture into rotational eigenstates /J, m > of the target molecule, as well as the thermal averaged rate coefficients are calculated for a number ion-dipole and ion-quadrupole systems for the temperature range 10 < or - T (deg K) < or - 1000.
