| Popis: | Two-photon transitions may proceed via a mechanism not involving virtually excited intermediate states. This mechanism may account for the largest contribution to the 2-photon cross section in polar mols. if the dipole moment strongly alters with excitation. Possible consequences for the 2-photon detection of forbidden states in polar polyene systems are discussed. CAN 97:100809 73-1 Optical, Electron, and Mass Spectroscopy and Other Related Properties |
