Transient Raman snapshots of the twisted intramolecular charge transfer state

Optically triggered twisted intramolecular charge transfer (TICT) states in donor-acceptor chromophores form the molecular basis for designing bio-imaging probes that sense polarity, microviscosity or pH in vivo.[1] However, a lack of predictive understanding of the ‘twist’ localization has limited...
