The time-resolved optical Kerr effect was used to probe the ultrafast relaxation of four halogenated methanes, CHC&, CBrCl,, CHBr, and CFBr3. A 65 fs coherent laser pulse from a synchronously pumped antiresonant ring dye laser with Fourier components ranging over 300 cm-' is separated into a pump an
