β¦ Synopsis
In the two-photon visible dlssocmtlon of the lodobenzene utlon, laser pulse shape IS ununportant when colhslonal relaxation 1s slow compared to the tune between pulses but becomes Important when the relaxation rate is comparable to tlmc between pulses The dlssoclatlon can be simulated usmg an mterrud energy-governed computer model.

The production of molecular and atomic ions has been measured for CO. N2 and O2 with 1064 and 532 nm 40 ps pulses in the 1012-10\*4 W cm" \_ rntensity range. A simultaneous ionization-dissociation process occurs at lower intensities, while a sequential process appears in oxygen at higher intensities
Multiphoton ionisation and dissociation of NO 2 has been studied experimentally at 375 nm for laser pulse widths of 10 ns and 50 fs. The parent NO 2 ion peak is not seen in the ns data. In all spectra, the main peak observed is due to the ionisation of the NO molecule which results from the dissocia
