| Summary:

We discuss our recent theoretical work on vibronic coupling mechanisms in a
model energy transfer system in the context of previous 2DEV experiments on a
natural light-harvesting system, light-harvesting complex II (LHCII), where
vibronic signatures were suggested to be involved in energy transfer. In this
comparison, we directly assign the vibronic coupling mechanism in LHCII as
arising from Herzberg-Teller activity and show how this coupling modulates the
energy transfer dynamics in this photosynthetic system.
