Ionic rotational selection rules for (n + 1) resonant enhanced multiphoton ionization

Abstract

We derive a selection rule for production of ionic rotational states in resonant enhanced multiphoton ionization (REMPI) of diatomic molecules. This selection rule enables a separation of both the particular symmetry components of the ionic rovibronic state and the even (gerade) and odd (ungerade) partial wave components of the electronic continuum even in heteronuclear molecules. The extreme sensitivity of the ionic rotational spectra to the symmetry of states allows one to influence the population of ionic rotational states through careful choices of REMPI schemes.
