We show that amplified spontaneous emission (ASE) can significantly influence population transfer between electronically excited molecular states. Such transfer can lead to anomalous conclusions being drawn from collisional energy transfer studies. We illustrate this point by considering two apparently conflicting studies involving E0(g)(+)(P-3(2)) to D0(u)(+)(P-3(2)) collisional transfer in I-2 and show that both sets of results can be reproduced when the ASE process is correctly identified and controlled.
