✦ Synopsis

We present a new procedure for the determination of the kinetic energy spectra of molecules undergoing multiphoton above-threshold dissociation (ATD) in intense laser fields. The method is based on the extension of the non-Hermitian Floquet theory and an integral equation formulation of the partial rates. The non-Hermitian Floquet Hamiltonian is discretized by means of the complex-scaling generalized pseudospectral technique, and a back rotation procedure is introduced for extracting the partial widths from the total resonance wavefunctions. The method is applied to the study of the ATD energy spectra of H~-molecular ions in intense (775 nm) laser fields.

CH(A \*A-X %) emission was observed following multiple photon dissociation of ketene with an ArF laser. For rotational levels with N' from 14 to 19 the symmetric A component of the emission had higher intensity than the antisymmetric and the opposite was observed for levels with N' between 20 and 23
