Cross Sections for Two-Photon Absorption and Geometric Dimensions of Electron Clouds of Hydroxybenzene Molecules

摘要

Cross sections for two-photon absorption of hydroxybenzenes at the 532-nm wavelength of the second harmonic of a Nd : YAG laser are measured. The results are interpreted by means of a semiempirical model, which allows one to estimate the dimensions of effective π-electron clouds of phenol, hydroquinone, resorcin, pyrocatechin, and bromohydroquinone.
