Abstract :
Tip-enhanced Raman spectroscopy at cryogenic temperatures probes the intrinsic linewidths of vibrational modes. Temperature dependent investigation of small ensembles reveals ultrafast vibrational relaxation dynamics, conformational heterogeneity, and single molecule fluctionality on the time scale of seconds.
