Description

Photoionisation efficiency (PIE)-spectra are measured for small (N2O)n-clusters, n=2 ... 8, using synchrotron radiation from the electron storage ring BESSY at Berlin. Ionisation thresholds are reported. Resonances in the wavelength-range 97 ... 100 nm for n>2 are attributed to exciton absorption with N2O-Rydberg levels, series I and II parentage. This interpretation is supported by measurements of the PIE of mixed benzonitrile x (N2O)n clusters where benzonitrile serves as a monitor for photon absorption in N2O at energies above the ionisation limit of benzonitrile.
