Abstract

During the last decades the vibrational population lifetimes and energy-transfer processes of small organic molecules have been investigated with many different techniques. One method of investigation is by exciting a significant fraction of the molecules with an intense infrared pump pulse. This will result in a bleaching of the sample if the vibration has an anharmonic progression. The excited system can be probed by measuring the transmission of the sample with a weak delayed second pulse.[1-3]
