Aliphatic side chains on PAHs shift certain infrared band intensity ratios, especially in small molecules, which can mislead ionization-state estimates, though the main diagnostic grid still applies with possible calibration.
Shiva is a new simulation tool that computes time-dependent dust size distributions and band gap energy evolution for HAC grains under photo-processing, sputtering, and shattering in specified interstellar conditions.
