We present results of extensive configuration interaction calculations of absorption oscillator strengths for transitions in Mn ii from the ground a 7 S 3 state to the lower 7 P o J and 5 P o J states. Of particular importance are the weak transitions to the y 7 P o J and x 7 P o J levels, which themselves strongly interact. These weaker lines are important in determining the interstellar abundance of Mn. We have also extended these calculations to examine intercombination lines of the form a 7 S 3 – 5 P o J .
