raman spectroscopy532 nm · pass B
reported peaks (cm⁻¹): 335, 412, 797, 910
notessubmitter remarks + registry
Time-resolved Raman shows that the 797 cm⁻¹ peak reappears in pulses of approximately 90 minutes after photobleaching. The interval is independent of pump fluence over a factor of ten and persists through a cooling cycle to 90 K. Mechanism not understood.
