✦ Synopsis
The multiple-photon absorption behavior of a series of alkyl chlorides and a number of hexadiene isomers has been examined in order to elucidate the dependence of absorption cross section on fluence. Measurements of absorbed energy via a photoacoustic technique show that, while a high density of states is necessary for an absorption cross section linear in fluence. other factors are also important. A photoacoustic technique for measuring absorbed energy by weakly absorbing molecules at low pressure is described.
