Transient ultrafast coherent spectroscopy of 2-propanol

We use transient coherent spontaneous Raman spectroscopy to measure the coherence lifetimes of vibrational states in liquid propanol. By creating single-photon-level collective excitations of the vibrational states in the system we observe coherence oscillations due to simultaneous excitation of the 2885 cm$^{\mathrm{-1}}$, 2938 cm$^{\mathrm{-1}}$, and 2976 cm$^{\mathrm{-1}}$ modes. These lifetimes and oscillation frequencies agree with frequency-domain lineshape measurements.
