Our protocol is particularly powerful for looking into the structure and dynamics of pi-conjugated molecules in the initial stage of chemical and biochemical reactions. This technique has a little bit higher sensitivity and makes the measurement t

Details of signal generation and optimization, measurement, data acquisition, and data handling for a femtosecond time-resolved near-IR stimulated Raman spectrometer are described. A near infrared stimulated Raman study on the excited-state dynamics of β-carotene in toluene is shown as a representative application.
