Abstract

By using time-resolved coherent Raman scattering, closely spaced vibrational resonances are simultaneously excited and subsequently monitored over long, nanosecond time intervals. Coherent superposition of molecular transitions leads to dramatic oscillations of the picosecond anti-Stokes scattering signals. Experimental data are presented for the ν1 mode of CH4 in supersonic expansions at low rotational temperatures (TROT ≥ 25). Our time-domain data are in good agreement with spectroscopic results. The corresponding frequency resolution of ≲3 × 10−3 cm−1 suggests that this method of Fourier-transform Raman spectroscopy may prove useful in high-resolution molecular spectroscopy.
