By using a combination of an initial pump pulse and a degenerate four-wave mixing process, we show that an interrogation of the vibrational dynamics occurring in different electronic states of molecules is possible. The technique is applied to iodine

A feedback-controlled optimization in a femtosecond coherent-anti Stokes Raman scattering (CARS) process is applied to selectively excite or suppress vibrational modes in the gas and liquid phase. The optimal control experiments are performed on carb

Femtosecond time-resolved coherent anti-Stokes Raman scattering (fs-CARS) results in spectra that, as a function of the probe delay time, yield information about the dynamics of the coherently excited vibrational modes. A change of the shape of the e

We present a comparison of results obtained by Raman and fs coherent anti-Stokes Raman scattering (CARS) spectroscopy on four molecules with puckered rings, analyzing the ring puckering band progressions. The dynamics are probed in gas and liquid pha

Femtosecond time-resolved coherent anti-Stokes Raman scattering (fs-CARS) gives access to ultrafast molecular dynamics. Due to the spectrally broad laser pulses, usually poorly resolved spectra result from this spectroscopy. However, it can be demons

Femtosecond laser pulses are spectrally broad and therefore coherently excite several molecular modes. While the temporal resolution is high, usually no mode-selective excitation is possible. In this work, we demonstrate that, by phase shaping one of

Femtosecond time-resolved coherent anti-Stokes Raman scattering (fs-CARS) gives access to ultrafast molecular dynamics. However, the gain of the temporal resolution entails a poor spectral resolution due to the inherent spectral width of the femtosec

The use of four‐wave mixing techniques in femtosecond time‐resolved spectroscopy has considerable advantages. Due to the many degrees of freedom offered e.g. by coherent anti‐Stokes Raman scattering (CARS), the dynamics even of complex systems

Femtosecond (fs) pulses are spectrally broad, and therefore, a selective excitation of specific vibrational modes of molecules is usually not achieved in ultrafast spectroscopy. This chapter provides an introduction to two experiments: answering ques
