N2 - After intense infrared excitation with 10 ps pulses, transient transmission spectra in the CH stretching region are measured for the first time by the help of separately tunable probing pulses (10 ps) for poly-propylene, -octene and -hexadecene in liquid solution. A vibrational bottleneck with rapid redistribution (<5 ps) and slower population decay is indicated by the observed absorption changes. New spectral information is obtained and compared with related results on octane and hexadecane.
